8eb5e6746f iotests: Use Python byte strings where appropriate
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.

bb2e16e90b scripts/device-crash-test: Remove devices that are not user_creatable anymore
Devices that are derived from TYPE_SYS_BUS_DEVICE are not user_creatable
anymore by default, and some others have been marked as non-user_creatable
manually, so we can remove these devices from the "ignore"-list in the
device-crash-test script.

4c9ab1e693 scripts: Remove check-qerror.sh
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.

Add a new Coccinelle script which replaces uses of the inplace
byteswapping functions *_to_cpus() and cpu_to_*s() with their
not-in-place equivalents. This is useful for where the swapping
is done on members of a packed struct -- taking the address
of the member to pass it to an inplace function is undefined

8c643361ee qapi: Add comments to aid debugging generated introspection
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:

| @@ -14755,6 +15240,7 @@
|          { "name", QLIT_QSTR("[485]"), },
|          {}

|      QLIT_QDICT(((QLitDictEntry[]) {

event_test_emit().

Drop the argument, and pass &error_abort to the QObject output visitor
and @qmp_emit instead.

66e9d20ee0 checkpatch: allow space in more places before a bracket
Allow a space between a colon and subsequent opening bracket.  This
sequence may occur in inline assembler statements like

	asm(
		"ldr %[out], [%[in]]\n\t"
		: [out] "=r" (ret)
		: [in] "r" (addr)
	);

Allow a space between a comma and subsequent opening bracket.  This
sequence may occur in designated initializers.

To ease backporting the patch, I am also changing the comma-bracket
detection (added in QEMU by commit 409db6eb71)
to use the same regex as brackets and colons (as done independently
by Linux commit daebc534ac15f991961a5bb433e515988220e9bf).

1f214ee1b8 qapi: Do not expose "allow-preconfig" in query-qmp-schema
According to commit 047f7038f5, option --preconfig

    [...] allows pausing QEMU in the new RUN_STATE_PRECONFIG state,
    allowing the configuration of QEMU from QMP before the machine
    jumps into board initialization code of machine_run_board_init()

    The intent is to allow management to query machine state and
    additionally configure it using previous query results within one
    QEMU instance (i.e. eliminate the need to start QEMU twice, 1st to
    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.

e20122ff0f checkpatch: handle token pasting better
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.

0708e6476f travis: add gcovr summary for GCOV build
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.

d626b6c1ae qapi-introspect: add preprocessor conditions to generated QLit
This commit adds 'ifcond' conditions to top-level QLit objects.
Future work will add them to object and enum type members, i.e. within
QLit objects.

Extend the QLit generator to_qlit() to accept (@obj, @cond) tuples in
addition to just @obj.  The tuple causes the QLit generated for
objects for @obj with #if/#endif conditions for @cond.

See generated tests/test-qmp-introspect.c. Example diff after this

40bb13766a qapi-introspect: modify to_qlit() to append ',' on level > 0
The following patch is going to break list entries with #if/#endif, so
they should have the trailing ',' as suffix.

ded9fc28b5 qapi: add #if/#endif helpers
Add helpers to wrap generated code with #if/#endif lines.

A later patch wants to use QAPIGen for generating C snippets rather
than full C files with copyright headers etc.  Splice in class
QAPIGenCCode between QAPIGen and QAPIGenC.

Add a 'with' statement context manager that will be used to wrap
generator visitor methods.  The manager will check if code was
generated before adding #if/#endif lines on QAPIGenCSnippet
objects. Used in the following patches.

4fca21c1b0 qapi: leave the ifcond attribute undefined until check()
We commonly initialize attributes to None in .init(), then set their
real value in .check().  Accessing the attribute before .check()
yields None.  If we're lucky, the code that accesses the attribute
prematurely chokes on None.

It won't for .ifcond, because None is a legitimate value.

Leave the ifcond attribute undefined until check().

2cbc94376e qapi: pass 'if' condition into QAPISchemaEntity objects
Built-in objects remain unconditional.  Explicitly defined objects use
the condition specified in the schema.  Implicitly defined objects
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
enough for now.
