6699ae6a8e decodetree: Allow multiple input files
While it would be possible to concatenate input files with make,
passing the original input files to decodetree.py allows us to
generate error messages which allows compilation environments
(read: emacs) to next-error to the correct input file.

3a7be55465 decodetree: Remove "insn" argument from trans_* expanders
This allows trans_* expanders to be shared between decoders
for 32 and 16-bit insns, by not tying the expander to the
size of the insn that produced it.

This change requires adjusting the two existing users to match.

f5177798d8 scripts: report on author emails that are mangled by the mailing list
In some cases the Author: email address in patches submitted to the
list gets mangled such that it says

    John Doe via Qemu-devel <qemu-devel@nongnu.org>

This change is a result of workarounds for DMARC policies.

Subsystem maintainers accepting patches need to catch these and fix
them before sending pull requests, so a checkpatch.pl test is highly
desirable.

bf43b29df4 iotests: Explicitly bequeath FDs in Python
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.

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.

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.

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]"), },
|          {}

	asm(

		: [in] "r" (addr)

Allow a space between a comma and subsequent opening bracket.  This

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.

9f88c66211 qapi-types: add #if conditions to types & visitors
