QAPIDoc uses a state machine to for processing of documentation lines.
Its state is encoded as an enum QAPIDoc._state (well, as enum-like
class actually, thanks to our infatuation with Python 2).
All we ever do with the state is calling the state's function to
process a line of documentation. The enum values effectively serve as
handles for the functions.
Eliminate the rather wordy indirection: store the function to call in
QAPIDoc._append_line. Update and improve comments.

Documentation comments follow a certain structure: First, we have a text
with a general description (called QAPIDoc.body). After this,
descriptions of the arguments follow. Finally, we have a part that
contains various named sections.
The code doesn't show this structure, but just checks various attributes
that indicate indirectly which part is being processed, so it happens to
do the right set of things in the right phase. This is hard to follow,
and adding support for documentation of features would be even harder.
This patch restructures the code so that the three parts are clearly
separated. The code becomes a bit longer, but easier to follow. The
resulting output remains unchanged.

Sometimes, the behaviour of QEMU changes without a change in the QMP
syntax (usually by allowing values or operations that previously
resulted in an error). QMP clients may still need to know whether
they can rely on the changed behavior.
Let's add feature flags to the QAPI schema language, so that we can make
such changes visible with schema introspection.
An example for a schema definition using feature flags looks like this:
{ 'struct': 'TestType',
'data': { 'number': 'int' },
'features': [ 'allow-negative-numbers' ] }
Introspection information then looks like this:
{ "name": "TestType", "meta-type": "object",
"members": [
{ "name": "number", "type": "int" } ],
"features": [ "allow-negative-numbers" ] }
This patch implements feature flags only for struct types. We'll
implement them more widely as needed.

In commit f2a3b549e3 we updated our u-boot blob

Apart from defconfig (which is a no-op),
allyesconfig/allnoconfig/randcondfig can be implemented simply by ignoring

respectively by "true", "false" or a random value.
However, allyesconfig and randconfig do not quite work, because all the
files for hw/ARCH/Kconfig are sourced and therefore you could end up
enabling some ARM boards in x86 or things like that. This is left for
future work, but I am leaving it in to help debugging minikconf itself.

The make_device_config.sh script is replaced by minikconf, which
is modified to support the same command line as its predecessor.
The roots of the parsing are default-configs/*.mak, Kconfig.host and
hw/Kconfig. One difference with make_device_config.sh is that all symbols
have to be defined in a Kconfig file, including those coming from the
configure script. This is the reason for the Kconfig.host file introduced
in the previous patch. Whenever a file in default-configs/*.mak used
$(...) to refer to a config-host.mak symbol, this is replaced by a
Kconfig dependency; this part must be done already in this patch
for bisectability.

There are three parts in the semantic analysis:
1) evaluating expressions. This is done as a simple visit
of the Expr nodes.
2) ordering clauses. This is done by constructing a graph of variables.
There is an edge from X to Y if Y depends on X, if X selects Y, or if
X appears in a conditional selection of Y; in other words, if the value
of X can affect the value of Y. Each clause has a "destination" variable
whose value can be affected by the clause, and clauses will be processed
according to a topological sorting of their destination variables.
Defaults are processed after all other clauses with the same destination.
3) deriving the value of the variables. This is done by processing
the clauses in the topological order provided by the previous step.
A "depends on" clause will force a variable to False, a "select" clause
will force a variable to True, an assignment will force a variable
to its RHS. A default will set a variable to its RHS if it has not
been set before. Because all variables have a default, after visiting
all clauses all variables will have been set.

This implements a scanner and recursive descent parser for Kconfig-like
configuration files. The only "action" of the parser is for now to
detect undefined variables and process include files.
The main differences between Kconfig and this are:
* only the "bool" type is supported
* variables can only be defined once
* choices are not supported (but they could be added as syntactic
sugar for multiple Boolean values)
* menus and other graphical concepts (prompts, help text) are not
supported
* assignments ("CONFIG_FOO=y", "CONFIG_FOO=n") are parsed as part
of the Kconfig language, not as a separate file.
The idea was originally by Ákos Kovács, but I could not find his
implementation so I had to redo it.

We generally put implicitly defined types in whatever module triggered
their definition. This is wrong for array types, as the included test
case demonstrates. Let's have a closer look at it.
Type 'Status' is defined sub-sub-module.json. Array type ['Status']
occurs in main module qapi-schema-test.json and in
include/sub-module.json. The main module's use is first, so the array
type gets put into the main module.
The generated C headers define StatusList in qapi-types.h. But
include/qapi-types-sub-module.h uses it without including
qapi-types.h. Oops.
To fix that, put the array type into its element type's module.
Now StatusList gets generated into qapi-types-sub-module.h, which all
its users include.

The #include directives to pull in sub-modules use file names relative
to the main module. Works only when all modules are in the same
directory, or the main module's output directory is in the compiler's
include path. Use relative file names instead.
The dummy variable we generate to avoid empty .o files has an invalid
name for sub-modules in other directories. Fix that.
Both messed up in commit 252dc3105f "qapi: Generate separate .h, .c
for each module". Escaped testing because tests/qapi-schema-test.json
doesn't cover sub-modules in other directories, only
tests/qapi-schema/include-relpath.json does, and we generate and
compile C code only for the former, not the latter. Fold the latter
into the former. This would have caught the mistakes fixed in this
commit.

This is a simple move of Python code that wraps common QEMU
functionality, and are used by a number of different tests
and scripts.
By treating that code as a real Python module, we can more easily:
* reuse code
* have a proper place for the module's own unittests
* apply a more consistent style
* generate documentation

This reverts commit 7bd2634905.
The commit applied the events' conditions to the members of enum
QAPIEvent. Awkward, because it renders QAPIEvent unusable in
target-independent code as soon as we make an event target-dependent.
Reverting this has the following effects:
* ui/vnc.c can remain target independent.
* monitor_qapi_event_conf[] doesn't have to muck around with #ifdef.
* query-events again doesn't reflect conditionals. I'm going to
deprecate it in favor of query-qmp-schema.
Another option would be to split target-dependent parts off enum
QAPIEvent into a target-dependent enum. Doesn't seem worthwhile right
now.

Having to include qapi-events.h just for QAPIEvent is suboptimal, but
quite tolerable now. It'll become problematic when we have events
conditional on the target, because then qapi-events.h won't be usable

We neglect to call .visit_module() for the special module we use for
built-ins. Harmless, but clean it up anyway. The
tests/qapi-schema/*.out now show the built-in module as 'module None'.
Subclasses of QAPISchemaModularCVisitor need to ._add_module() this
special module to enable code generation for built-ins. When this
hasn't been done, QAPISchemaModularCVisitor.visit_module() does
nothing for the special module. That looks like built-ins could
accidentally be generated into the wrong module when a subclass
neglects to call ._add_module(). Can't happen, because built-ins are
all visited before any other module. But that's non-obvious. Switch
off code generation explicitly.
Rename QAPISchemaModularCVisitor._begin_module() to
._begin_user_module().
New QAPISchemaModularCVisitor._is_builtin_module(), for clarity.

The cmd() method of the QEMUQtestProtocol class sends a qtest command
to QEMU but doesn't wait for the return message ("OK", "FAIL", "ERR").
Because of this, it can return control to the caller before the
command has actually finished.
In cases like clock_step or clock_set this means that cmd() can return
before all the timers triggered by the clock change have been fired.
This can be fixed by making cmd() wait for the output of the qtest
command.
This fixes iotests 093 and 136, which are flaky since commit
8258292e18 when the machine is under heavy workload.

In checkpatch we attempt to check for and warn about
block comments which start with /* or /** followed by a
non-blank. Unfortunately a bug in the regex meant that
we would incorrectly warn about comments starting with
"/**" with no following text:
git show 9813dc6ac3954d58ba16b3920556f106f97e1c67|./scripts/checkpatch.pl -
WARNING: Block comments use a leading /* on a separate line
#34: FILE: tests/libqtest.h:233:
+/**
The sequence "/\*\*?" was intended to match either "/*" or "/**",
but Perl's semantics for '?' allow it to backtrack and try the
"matches 0 chars" option if the "matches 1 char" choice leads to
a failure of the rest of the regex to match. Switch to "/\*\*?+"
which uses what perlre(1) calls the "possessive" quantifier form:
this means that if it matches the "/**" string it will not later
backtrack to matching just the "/*" prefix.
The other end of the regex is also wrong: it is attempting
to check for "/* or /** followed by something that isn't
just whitespace", but [ \t]*.+[ \t]* will match on pure
whitespace. This is less significant but means that a line
with just a comment-starter followed by trailing whitespace
will generate an incorrect warning about block comment style
as well as the correct error about trailing whitespace which
a different checkpatch test emits.

This commit introduces a way to do simple printf style logging of probe
points using systemtap. In particular it creates another set of tapsets,
one per emulator:
/usr/share/systemtap/tapset/qemu-*-log.stp
These pre-define probe functions which simply call printf() on their
arguments. The printf() format string is taken from the normal
trace-events files, with a little munging to the format specifiers
to cope with systemtap's more restrictive syntax.
With this you can now do
$ stap -e 'probe qemu.system.x86_64.log.qio*{}'

This tool is clever in that it will automatically change the
SYSTEMTAP_TAPSET env variable to point to the directory containing the
right set of probes for the QEMU binary path you give it. This is useful
if you have QEMU installed in /usr but are trying to test and trace a
binary in /home/berrange/usr/qemu-git. In that case you'd do
$ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*'
And it'll make sure /home/berrange/usr/qemu-git/share/systemtap/tapset
is used for the trace session
The 'qemu-trace-stap' script takes a verbose arg so you can understand
what it is running
$ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*'
Using tapset dir '/home/berrange/usr/qemu-git/share/systemtap/tapset' for binary '/home/berrange/usr/qemu-git/bin/qemu-system-x86_64'
Compiling script 'probe qemu.system.x86_64.log.qio* {}'
Running script, <Ctrl>-c to quit
...trace output...
It can enable multiple probes at once
$ qemu-trace-stap run qemu-system-x86_64 'qio*' 'qcrypto*' 'buffer*'
By default it monitors all existing running processes and all future
launched proceses. This can be restricted to a specific PID using the
--pid arg
$ qemu-trace-stap run --pid 2532 qemu-system-x86_64 'qio*'
Finally if you can't remember what probes are valid it can tell you
$ qemu-trace-stap list qemu-system-x86_64
ahci_check_irq
ahci_cmd_done
ahci_dma_prepare_buf
ahci_dma_prepare_buf_fail
ahci_dma_rw_buf

Or list just those matching a prefix pattern

The '%m' format instructs glibc's printf()/syslog() implementation to
insert the contents of strerror(errno). Since this is a glibc extension
it should generally be avoided in QEMU due to need for portability to a
variety of platforms.
Even though vfio is Linux-only code that could otherwise use "%m", it
must still be avoided in trace-events files because several of the
backends do not use the format string and so this error information is
invisible to them.
The errno string value should be given as an explicit trace argument
instead, making it accessible to all backends. This also allows it to
work correctly with future patches that use the format string with
systemtap's simple printf code.

When generating the trace-events-all file, the build system simply
concatenates all the individual trace-events files. If any one of those
files does not have a final newline, the printf format string will have
the contents of the first line of the next file appended to it, which is
usually a '#' comment.

The qapi_event_send_FOO() functions emit events like this:
QMPEventFuncEmit emit;
emit = qmp_event_get_func_emit();
if (!emit) {
return;
}
qmp = qmp_event_build_dict("FOO");
[put event arguments into @qmp...]
emit(QAPI_EVENT_FOO, qmp);
The value of qmp_event_get_func_emit() depends only on the program:
* In qemu-system-FOO, it's always monitor_qapi_event_queue.
* In tests/test-qmp-event, it's always event_test_emit.
* In all other programs, it's always null.
This is exactly the kind of dependence the linker is supposed to
resolve; we don't actually need an indirection.
Note that things would fall apart if we linked more than one QAPI
schema into a single program: each set of qapi_event_send_FOO() uses
its own event enumeration, yet they share a single emit function.
Which takes the event enumeration as an argument. Which one if
there's more than one?
More seriously: how does this work even now? qemu-system-FOO wants
QAPIEvent, and passes a function taking that to
qmp_event_set_func_emit(). test-qmp-event wants test_QAPIEvent, and
passes a function taking that to qmp_event_set_func_emit().
It works by type trickery, of course:
typedef void (*QMPEventFuncEmit)(unsigned event, QDict *dict);
void qmp_event_set_func_emit(QMPEventFuncEmit emit);
QMPEventFuncEmit qmp_event_get_func_emit(void);
We use unsigned instead of the enumeration type. Relies on both
enumerations boiling down to unsigned, which happens to be true for
the compilers we use.
Clean this up as follows:
* Generate qapi_event_send_FOO() that call PREFIX_qapi_event_emit()
instead of the value of qmp_event_set_func_emit().
* Generate a prototype for PREFIX_qapi_event_emit() into
qapi-events.h.
* PREFIX_ is empty for qapi/qapi-schema.json, and test_ for
tests/qapi-schema/qapi-schema-test.json. It's qga_ for
qga/qapi-schema.json, and doc-good- for
tests/qapi-schema/doc-good.json, but those don't define any events.
* Rename monitor_qapi_event_queue() to qapi_event_emit() instead of
passing it to qmp_event_set_func_emit(). This takes care of
qemu-system-FOO.
* Rename event_test_emit() to test_qapi_event_emit() instead of
passing it to qmp_event_set_func_emit(). This takes care of
tests/test-qmp-event.
* Add a qapi_event_emit() that does nothing to stubs/monitor.c. This
takes care of all other programs that link code emitting QMP events.
* Drop qmp_event_set_func_emit(), qmp_event_get_func_emit().

QTAILQ is a doubly linked list, with a pointer-to-pointer to the last
element from the head, and the previous element from each node.
But if you squint enough, QTAILQ becomes a combination of a singly-linked
forwards list, and another singly-linked list which goes backwards and
is circular. This is the idea that lets QTAILQ implement reverse
iteration: only, because the backwards list points inside the node,
accessing the previous element needs to go two steps back and one
forwards.
What this patch does is implement it in these terms, without actually
changing the in-memory layout at all. The coexistence of the two lists
is realized by making QTAILQ_HEAD and QTAILQ_ENTRY unions of the forwards
pointer and a generic QTailQLink node. Thq QTailQLink can walk the list in
both directions; the union is needed so that the forwards pointer can
have the correct type, as a sort of poor man's template. While there
are other ways to get the same layout without a union, this one has
the advantage of simpler operation in the debugger, because the fields
tqh_first and tqe_next still exist as before the patch. Those fields are
also used by scripts/qemugdb/mtree.py, so it's a good idea to preserve them.
The advantage of the new representation is that the two-back-one-forward
dance done by backwards accesses can be done all while operating on
QTailQLinks. No casting to the head struct is needed anymore because,
even though the QTailQLink's forward pointer is a void *, we can use
typeof to recover the correct type. This patch only changes the
implementation, not the interface. The next patch will remove the head
struct name from the backwards visit macros.

gtester is deprecated by upstream glib (see for example the announcement
at https://blog.gtk.org/2018/07/11/news-from-glib-2-58/) and it does
not support tests that call g_test_skip in some glib stable releases.
glib suggests instead using Automake's TAP support, which gtest itself
supports since version 2.38 (QEMU's minimum requirement is 2.40).
We do not support Automake, but we can use Automake's code to beautify
the TAP output. I chose to use the Perl copy rather than the shell/awk
one, with some changes so that it can accept TAP through stdin, in order
to reuse Perl's TAP parsing package. This also avoids duplicating the
parser between tap-driver.pl and tap-merge.pl.

Drop the explicit values. No change now, but it will avoid gaps in
the values when we later add support for 'if' conditions. Avoiding
such gaps will save us the trouble of changing the ENUM_lookup[]
tables to work without a sentinel.
We'll have to take care to ensure the headers required by the 'if'
conditions get always included before the generated QAPI code.
Fortunately, our convention to include "qemu/osdep.h" first in any .c
ensures that's the case for our CONFIG_FOO macros.

Currently the log backend prints the process id of QEMU at the start
of each output line, but since threads share the same PID there is no
clear distinction between their outputs.
Having the thread id present in the log makes it easier to see when
output comes from different threads. E.g.:
12423@1538597569.672527:qemu_mutex_lock waiting on mutex 0x1103ee60 (/root/qemu/util/main-loop.c:236)
...
12430@1538597569.503928:qemu_mutex_unlock released mutex 0x1103ee60 (/root/qemu/cpus.c:1238)
12431@1538597569.503937:qemu_mutex_locked taken mutex 0x1103ee60 (/root/qemu/cpus.c:1257)
^here
In the above, 12423 is the main process id and 12430 & 12431 are the
two vcpu threads.

POSIX requires $PWD to be reliable, and we expect all
shells used by qemu scripts to be relatively close to
POSIX. Thus, it is smarter to avoid forking the pwd
executable for something that is already available in
the environment.
So replace it with the following:
sed -i 's/\(`pwd`\|\$(pwd)\)/$PWD/g' $(git grep -l pwd)
Then delete a pointless line assigning PWD to itself.

Python 3.4 introduced the inheritable attribute for FDs. At the same
time, it changed the default so that all FDs are not inheritable by
default, that only inheritable FDs are inherited to subprocesses, and
only if close_fds is explicitly set to False.
Adhere to this by setting close_fds to False when working with
subprocesses that may want to inherit FDs, and by trying to
set_inheritable() on FDs that we do want to bequeath to them.

Since byte strings are no longer the default in Python 3, we have to
explicitly use them where we need to, which is mostly when working with
structures. It also means that we need to open a file in binary mode
when we want to use structures.
On the other hand, we have to accomodate for the fact that some
functions (still) work with byte strings but we want to use unicode
strings (in Python 3 at least, and it does not matter in Python 2).
This includes base64 encoding, but it is most notable when working with
the subprocess module: Either we set universal_newlines to True so that
the default streams are opened in text mode (hence this parameter is
aliased as "text" as of 3.7), or, if that is not possible, we have to
decode the output to a normal string.

qerror.h contains leftovers from the now-defunct QError API.
There's only a handful of string macros left, and no one is supposed
to add anything else. The check-qerror.sh script was used to make sure
that all definitions on the qerror.c and qerror.h files were sorted
alphabetically. The former was removed three years ago, and the latter
is now in a different location, so the script doesn't even work (as
a matter of fact the alphabetical order was broken last time someone
added a macro -also in 2015- and no one seemed to notice).
There's no point in fixing this script so let's just remove it.
The rogue macro is also moved to its correct location.

We consciously chose in commit 1a9a507b to hide QAPI type names
from the introspection output on the wire, but added a command
line option -u to unmask the type name when doing a debug build.
The unmask option still remains useful to some other forms of
automated analysis, so it will not be removed; however, when it
is not in use, the generated .c file can be hard to read. At
the time when we first introduced masking, the generated file
consisted only of a monolithic C string, so there was no clean
way to inject any comments.
Later, in commit 7d0f982b, we switched the generation to output
a QLit object, in part to make it easier for future addition of
conditional compilation. In fact, commit d626b6c1 took advantage
of this by passing a tuple instead of a bare object for encoding
the output of conditionals. By extending that tuple, we can now
interject strategic comments.
For now, type name debug aid comments are only output once per
meta-type, rather than at all uses of the number used to encode
the type within the introspection data. But this is still a lot
more convenient than having to regenerate the file with the
unmask operation temporarily turned on - merely search the
generated file for '"NNN" =' to learn the corresponding source
name and associated definition of type NNN.
The generated qapi-introspect.c changes only with the addition
of comments, such as:

query board specific parameters and 2nd for actual VM start using
query results for additional parameters).
The implementation is a bit of a hack: it splices in an additional
main loop before machine creation, in special runstate preconfig. New
command exit-preconfig exits that main loop. QEMU continues
initializing, creates the machine, and runs the good old main loop.
The replacement of the main loop is transparent to monitors.
Sadly, some commands expect initialization to be complete. Running
them in --preconfig's main loop violates their preconditions. Since
we don't really know which commands are safe, we use a whitelist.
This drags the concept of run state into the QMP core.
The whitelist is done as a command flag in the QAPI schema (commit
d6fe3d02e9). Drags the concept of run state further into the QAPI
language.
The command flag is exposed in query-qmp-schema (also commit
d6fe3d02e9). This makes it ABI.
I consider the whole thing an offensively ugly hack, but sometimes an
ugly hack is the best we can do to solve a problem people have.
The need described by the commit message quote above is genuine. The
proper solution would be a main loop that permits complete
configuration via QMP. This is out of reach, thus the hack.
However, even though the need is genuine, it isn't urgent: libvirt is
not going to use this anytime soon. Baking a hack into ABI before it
has any users is a bad idea.
This commit reverts the parts of commit d6fe3d02e9 that affect ABI
via query-qmp-schema. The commit did the following:
(1) Add command flag 'allow-preconfig' to the QAPI schema language
(2) Pass it to code generators
(3) Have the commands.py code generator pass it to the command
registry (so commit 047f7038f5 can use it as whitelist)
(4) Add 'allow-preconfig' to SchemaInfoCommand (neglecting to update
qapi-code-gen.txt section "Client JSON Protocol introspection")
(5) Set 'allow-preconfig': true for commands qmp_capabilities,
query-commands, query-command-line-options, query-status
Revert exactly (4), plus a bit of documentation added to
qemu-tech.info in commit 047f7038f5.
Shrinks query-qmp-schema's output from 126.5KiB to 121.8KiB for me.

[Straightforward conflict with commit d626b6c1ae resolved]
The mechanism to find possible type tokens can sometimes be confused and go into an
infinite loop. This happens for example in QEMU for a line that looks like
uint## BITS ##_t S = _S, T = _T; \
uint## BITS ##_t as, at, xs, xt, xd; \
Because the token pasting operator does not have a space before _t, it does not
match $notPermitted. However, (?x) is turned on in the regular expression for
modifiers, and thus ##_t matches the empty string. As a result, annotate_values
goes in an infinite loop.
The solution is simply to remove token pasting operators from the string before
looking for modifiers. In the example above, the string uintBITS_t will be
evaluated as a candidate modifier. This is not optimal, but it works as long
as people do not write things like a##s##m, and it fits nicely into sub
possible.
For a similar reason, \# should be rejected always, even if it is not
at end of line or followed by whitespace.
The same patch was sent to the Linux kernel mailing list.

This gives a more useful summary, sorted by descending % coverage,
after the tests have run. The final numbers will give an idea if our
coverage is getting better or worse.
To keep the width sane we need to post process the file that the old
gcovr tool generates. This is done with a mix of sed, awk and column
in the scripts/coverage-summary.sh script.
As quite a lot of lines don't get covered at all we filter out all the
0% lines. If the file doesn't appear it is not being exercised.

Built-in objects remain unconditional. Explicitly defined objects use

inherit their condition from their users. For most of them, there is
exactly one user, so the condition to use is obvious. The exception
is wrapped types generated for simple union variants, which can be
shared by any number of simple unions. The tight condition would be
the disjunction of the conditions of these simple unions. For now,
use the wrapped type's condition instead. Much simpler and good

Matthias Maier and Arfrever Frehtes Taifersar Arahesis proposed to use
binary mode instead, with manual conversion from bytes to str. Works,
but opening with an explicit encoding is simpler, so do that.
Since Python 2's open() doesn't support the encoding parameter, we
need to suppress it with a version check.

uncovered. Such cases had to be worked around by either stating a dummy

Both options create redundant entities in qapi files for little profit.
With this patch it is not necessary anymore to add designated union
fields for every possible value of a discriminator enumeration.

The set_console() method is intended to ease higher level use cases
that require a console device.
The amount of intelligence is limited on purpose, requiring either the
device type explicitly, or the existence of a machine (pattern)
definition.
Because of the console device type selection criteria (by machine
type), users should also be able to define that. It'll then be used
for both '-machine' and for the console device type selection.
Users of the set_console() method will certainly be interested in
accessing the console device, and for that a console_socket property
has been added.

New option will be used to allow commands, which are prepared/need

to run in preconfig state, should be amended to not expect machine
in initialized state or deal with it.
For compatibility reasons, commands that don't use new flag
'allow-preconfig' explicitly are not permitted to run in
preconfig state but allowed in all other states like they used
to be.
Within this patch allow following commands in preconfig state:
qmp_capabilities
query-qmp-schema
query-commands
query-command-line-options
query-status
exit-preconfig
to allow qmp connection, basic introspection and moving to the next

Rework the update script slightly, add the unistd.h header and its
dependencies on all architectures.
This also removes the IA64 and MIPS from a KVM blacklist:
Linux dropped IA64, and there was never a reason to
exclude MIPS from kvm specifically - it was
excluded due to dependency of its unistd.h on sgidefs.h,
which we also import.

All the xen stable APIs define handle types of the form:
xen<subject of API>_handle
and some define additional handle types of the form:
xen<subject of API>_<purpose of handle>_handle
Examples of these are xenforeignmemory_handle and
xenforeignmemory_resource_handle.
Both of these types will be misparsed by checkpatch if they appear as the
first token in a line since, as types defined by an external library, they
do not conform to the QEMU CODING_STYLE, which suggests CamelCase.
A previous patch (5ac067a24a) added xendevicemodel_handle to the list
of types. This patch changes that to xen\w+_handle such that it will
match all Xen stable API handles of the forms detailed above.

We'll soon need an enumeration type that lists all the softmmu targets
that QEMU (the project) supports. Introduce @SysEmuTarget to
"common.json".
The enum constant @x86_64 doesn't match the QAPI convention of preferring
hyphen ("-") over underscore ("_"). This is intentional; the @SysEmuTarget
constants are supposed to produce QEMU executable names when stringified
and appended to the "qemu-system-" prefix. Put differently, the
replacement text of the TARGET_NAME preprocessor macro must be possible to
look up in the list of (stringified) enum constants.
Like other enum types, @SysEmuTarget too can be used for discriminator
fields in unions. For the @i386 constant, a C-language union member called
"i386" would be generated. On mingw build hosts, "i386" is a macro
however. Add "i386" to "polluted_words" at once.

Now that we can safely call QOBJECT() on QObject * as well as its
subtypes, we can have macros qobject_ref() / qobject_unref() that work
everywhere instead of having to use QINCREF() / QDECREF() for QObject
and qobject_incref() / qobject_decref() for its subtypes.
The replacement is mechanical, except I broke a long line, and added a
cast in monitor_qmp_cleanup_req_queue_locked(). Unlike
qobject_decref(), qobject_unref() doesn't accept void *.
Note that the new macros evaluate their argument exactly once, thus no
need to shout them.

This avoids checkpatch misparsing (as statements) long function
definitions or declarations, which sometimes start with constructs
like this:
static inline int xendevicemodel_relocate_memory(
xendevicemodel_handle *dmod, domid_t domid, ...
The type xendevicemodel_handle does not conform to Qemu CODING_STYLE,
which would suggest CamelCase. However, it is a type defined by the
Xen Project in xen.git. It would be possible to introduce a typedef
to allow the qemu code to refer to it by a differently-spelled name,
but that would obfuscate more than it would clarify.

Here "oob" stands for "Out-Of-Band". When "allow-oob" is set, it means
the command allows out-of-band execution.
The "oob" idea is proposed by Markus Armbruster in following thread:
https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg02057.html
This new "allow-oob" boolean will be exposed by "query-qmp-schema" as
well for command entries, so that QMP clients can know which commands
can be used in out-of-band calls. For example the command "migrate"
originally looks like:
{"name": "migrate", "ret-type": "17", "meta-type": "command",
"arg-type": "86"}
And it'll be changed into:
{"name": "migrate", "ret-type": "17", "allow-oob": false,
"meta-type": "command", "arg-type": "86"}
This patch only provides the QMP interface level changes. It does not
contain the real out-of-band execution implementation yet.

Replace the generated json string with a literal qobject. The later is
easier to deal with, at run time as well as compile time: adding #if
conditionals will be easier than in a json string.
The output of query-qmp-schema is not changed.
