a055308668 tests: don't set G_DEBUG=fatal-warnings on macOS
On macOS when BROKEN_POLL is set in GLib, our tests will periodically
trigger a warning:

  (process:50880): GLib-WARNING **: 02:54:15.272: poll(2) failed due to: Bad file descriptor.

Our code is inherantly racy, calling g_source_destroy which
removes the FD from the event thread poll asynchronously but
we close the FD immediately after g_source_destroy returns.

With poll() this results in POLLNVAL which we're ignoring, but
with select() it generates the BADF error on macOS.

We need to ignore the warnings on macOS to avoid abort()ing
our test programs.

Closes: https://gitlab.com/libvirt/libvirt/-/issues/303

b94239a61e meson: Use dicts to initialize cfg_data objects
Instead of creating an empty object and then setting keys one
at a time, it is possible to pass a dict object to
configuration_data(). This is nicer because it doesn't require
repeating the name of the cfg_data object over and over.

There is one exception: the 'conf' object, where we store values
that are used directly by C code. In that case, using a dict
object is not feasible for two reasons: first of all, replacing
the set_quoted() calls would result in awkward code with a lot
of calls to format(); moreover, since code that modifies it is
sprinkled all over the place, refactoring it would probably
make things more complicated rather than simpler.

654486bd57 syntax-check: sc_avoid_write: Don't use blanket file exceptions
Adding an exception for the whole file usually defeats the purpose of a
syntax check and is also likely to get forgotten once the file is
removed.

In case of the suggestion of using 'safewrite' instead of write even the
comment for safewrite states that the function needs to be used only in
certain cases.

Remove the blanket exceptions for files and use an exclude string
instead. The only instance where we keep the full file exception is for
src/libvirt-stream.c as there are multiple uses in example code in
comments where I couldn't find a nicer targetted wapproach.

4c69d64efa meson: Explicitly specify run_command's check parameter
An update to meson 0.61.1 meant that it started showing warnings due to the fact
that the default for run_command's 'check' parameter is going to change.  It
unveiled the fact that we were even missing that parameter in some calls where
we expected different outcome.  To make sure the behaviour does not change
specify the parameter explicitly.  In places where we check for the return code
the parameter should be 'false' so that meson does not fail.  In all other cases
the parameter should be set to 'true' to make sure possible failure also stops
meson.

The warning in meson was added in https://github.com/mesonbuild/meson/pull/9304

59c1bc3a0e Add a PCI/PCIe device VPD Parser
Add support for deserializing the binary PCI/PCIe VPD format and storing
results in memory.

The VPD format is specified in "I.3. VPD Definitions" in PCI specs
(2.2+) and "6.28.1 VPD Format" PCIe 4.0. As section 6.28 in PCIe 4.0
notes, the PCI Local Bus and PCIe VPD formats are binary compatible
and PCIe 4.0 merely started incorporating what was already present in
PCI specs.

Linux kernel exposes a binary blob in the VPD format via sysfs since
v2.6.26 (commit 94e6108803469a37ee1e3c92dafdd1d59298602f) which requires
a parser to interpret.

345996c620 meson: avoid bogus warnings from clang and g_autoptr
Clang has previously had trouble with G_DEFINE_AUTOPTR_CLEANUP_FUNC
generated code, thinking it was unused. We turn off -Wunused-function
to avoid tripping up on that with CLang.

New Clang has started having trouble with g_autoptr now too. In usage
scenarios where the variable is set, but never again read, it thinks
it is unused not realizing the destructor has useful side effects.
For this we have to skip -Wunused-but-set-variable on CLang.

Commit abab5c47f8 incorrectly
assumed we do not have any files that could be affected by

  sc_prohibit_reversed_compare_failure

due to the conditional assignment:

  _test_script_regex ?= \<init\.sh\>

so it removed the check.

Also remove the leftover assignment of test-lib.sh,
since any new code attempting to use the compare function
with reversed arguments should be rejected by review
for using shell instead of C or Python.

0af0b7d87d syntax-check: drop useless useless-if-before-free
With most of new code using g_auto for cleanup, contributors
are used to most of the free fucntions handling NULL gracefully.

Also, despite finding some occurrences in current codebase:
  avoid_if_before_free
  ~/libvirt/src/ch/ch_monitor.c: if (mon->vm)
        virObjectUnref(mon->vm);
  ~/libvirt/src/util/virresctrl.c: if (a_type->masks[cache])
        virBitmapFree(a_type->masks[cache]);
the check passes succesfully, because the script's logic:

  Exit status:
    0   one or more matches
    1   no match
    2   an error

does not play nicely with xargs:

  xargs exits with the following status:
       0      if it succeeds
     123      if any invocation of the command exited with status 1-125

The list of functions is also out of date - e.g. qemuCapsFree has
been renamed since.

This also helps eliminate one more Perl script per our programming
languages strategy: https://libvirt.org/programming-languages.html

457f4e6e1e meson: Don't check whether /usr/local/bin/grep is GNU grep
Since /usr/local is where ports live, it's reasonable to assume
that a grep binary found in there will have been installed via
ports and will thus be GNU grep.

8526abc454 meson: Look for GNU tools on macOS too
macOS is similar to FreeBSD in that it ships non-GNU versions
of several utilities that we need in the base system.

macOS actually includes GNU make already, but unfortunately due
to licensing reasons the tool is permanently stuck in 2006, so
even in that case users are better off installing a recent
version from Homebrew along with the dozens of other libvirt
dependencies that already need to be obtained that way.

Note that, unlike FreeBSD ports, Homebrew is fully consistent
in adding the 'g' prefix to the name of the GNU tools, so we
can detect GNU grep without additional hacks.

7cbcc9f888 meson: Check GNU sed's availability
As explained in the comment in build-aux/Makefile.in, the
version of sed included in the FreeBSD base system is not GNU
sed, which our syntax-check rules expect; as a result, many
checks will fail with

  gmake: gsed: No such file or directory
  /bin/sh: gsed: not found

Similarly to what we're already doing with GNU make and GNU
grep, look for GNU sed during the configuration step and fail
early if it's not available.

5254532e3a meson: Reorganize looking for programs
While this change doesn't look like it would improve things and
actually introduces a tiny bit of duplication, it's necessary in
order to prepares the stage for further changes.

6a023e943e meson: Print custom message when GNU grep is not installed
Currently, if GNU grep is not installed on a FreeBSD system the
configuration step will fail with

  Program grep found: YES (/usr/bin/grep)
  Program /usr/local/bin/grep found: NO

  ERROR: Program '/usr/local/bin/grep' not found

which is confusing and not very useful; after this change, the
message will be

  Program grep found: YES (/usr/bin/grep)
  Program /usr/local/bin/grep found: NO

  ERROR: Problem encountered: GNU grep not found

instead, which should do a better job helping the user figure
out that they need to install GNU grep from ports to proceed.

cae268f7b9 syntax-check: Run flake8 on all Python scripts
Currenty we only check files that end in .py, but we have at
least a couple of scripts that don't have that suffix and we
nonetheless want to keep compliant with the code style.

Extend the sc_flake8 syntax-check rule so that any file that
contains a Python 3 shebang is fed to flake8 too.
