Various projects are running tests under valgrind, and they are using
the GLib suppresions to avoid false-positive results.
While this is stored in a well-known path for some years, and easy to
figure out from the GLib prefix, it's better to expose it through a
proper pkgconfig variable so that it's easy to get it from any build
system.
Previously, `-Wl,--export-dynamic` was in `Libs` key of `gmodule-2.0.pc`,
even though `-Wl` is a compiler flag, rather than a linker one.
This caused issues with API reference builds in evolution-data-server,
which passes the output of `pkg-config --libs` through `--ldflags`
argument of `gtkdoc-scan`, which are forwarded unchanged to `ld`:
ld: unrecognized option '-Wl,--export-dynamic'
Let’s move the flag to `Cflags` so that the compiler can deal with it.

proxy-libintl defines ngettext() as a define in the header that points
to the actual symbol in the library which is g_libintl_ngettext().
Same with bind_textdomain_codeset().
If we are sorting something that is a multiple of sizeof(void*), we have
to ensure that we swap one pointer at a time since swapping using
sub-pointer-size stores invalidate the pointers (pointers have a hidden
validity tags that is invalidated when performing non-monotonic
operations such as storing only part of the pointers).
While touching this code also use G_ALIGNOF() instead of a macro that
is generated at configure time.

Meson supports tap protocol results parsing, allowing us to track better
the tests that are running (and the ones that are actually skipped) without
manually parsing the test output.
However this also implies that using the verbose mode for a test doesn't
show its output by default (unless there are failures).
Setting the main thread's scheduler settings is not reliably possible,
especially not if SELinux or similar mechanisms are used to limit what
can be done.
As such, get rid of all the complicated code that tried to do this
better and use a separate thread for spawning threads for the global
shared thread pool. These will always inherit the priority of the main
thread (or rather the thread that created the first shared thread pool).
Fixes https://gitlab.gnome.org/GNOME/glib/-/issues/2769
If proxy-libintl has already been configured before we get to glib, we
will pick that up in dependency('intl'), which then does compiler
checks on it. This was written to assume that the first check will not
find a subproject for libintl, so force it with allow_fallback: false.
Also update the proxy-libintl wrap file and get rid of the explicit
subproject() call.

This test assumes that pcre2 is not provided by a subproject, so force
it to be that. Explicitly allow fallback in the next check (although
it's implied already).
On some systems only `futex_time64` exists (e.g. riscv32) while on
others only `futex` exists (old Linux, 64 bit platforms), so it is
necessary to check for both and try calling both at runtime.
Additionally use the correct `struct timespec` definition. There is not
necessarily any relation between the libc's definition and the kernel's.
Specifically, the libc headers might use 64-bit `time_t` while the kernel
headers use 32-bit `__kernel_old_time_t` on certain systems.
To get around this problem we
a) check if `futex_time64` is available, which only exists on 32-bit
platforms and always uses 64-bit `time_t`.
b) otherwise (or if that returns `ENOSYS`), we call the normal `futex`
syscall with the `struct timespec` used by the kernel, which uses
`__kernel_long_t` for both its fields. We use that instead of
`__kernel_old_time_t` because it is equivalent and available in the
kernel headers for a longer time.
This will be used in upcoming commits to allow the previously-hardcoded
`/run` path to be set at configure time.
Most people will not want to change it from `/run`, even when building
test builds, as otherwise interaction with system mounts and services
will not work.

`join_paths()` automatically drops all preceding path elements if an
argument to it is an absolute path. The `/` is a tidier synonym for
`join_paths()`.
This introduces no functional changes.

This reverts commit 91f14cd058.
The freedesktop SDK, which is used by gnome-build-meta, only has Meson
0.63. Bumping GLib’s Meson dependency to 0.64 means that, at the moment,
GLib is not buildable in gnome-build-meta and hence can’t be tested in
nightly pipelines against other projects, etc.
That’s bad for testing GLib.
It’s arguably bad that we’re restricted to using an older version of
Meson than shipped by Debian Testing, but that’s a separate discussion
to be had.
Revert the Meson 0.64 dependency until the freedesktop SDK ships Meson ≥
0.64. This also means reverting the simplifications to use of
`gnome.mkenum_simple()`.

Meson now uses find_program() to get glib-mkenum from glib instead of
from system. That was already fixed at least in >=0.60 which is our
current minimum requirement.
Because Meson complains about using `configure_file(copy: true)`.

We need to ensure that all the expected macros and utilities are working
with all the supported C standards, so just repeat the tests with all
the ones the compiler supports.
It was previously only enabled (by default) on macOS, which led to
code being committed which triggered warnings, as that CI job is not
always run.
Avoid that risk by always enabling the warning.
The reasoning for using this warning is that explicit initialisation is
clearer than implicit. We also want to support GLib’s public headers
being used in projects which build with
`-Werror=missing-field-initializers`, but can’t easily enable the
warning for our public headers but not our internal code. So enable it
everywhere.
Make it a warning rather than an error, as there’s a risk that system
header changes will trigger it in distro release builds, which would
cause false build failures. By making it a warning, GLib developers can
build with `-Werror` and promote it to an error, while distros can
choose not to.

It should be enabled in all builds, not just CI builds. Otherwise
developers might miss it locally.

Allow one to override the invalid parameter handler if we have the
following items:
* _set_invalid_parameter_hander() or
_set_thread_local_parameter_handler()
* _CrtSetReportMode() as a function or macro
Currently, we are doing this on Visual Studio to allow GSpawn to work on
Windows as well as having the log writer support color output, as we
might be passing in file descriptors that are invalid, which will cause
the CRT to abort unless the default invalid parameter handler is
overridden.
Given that it can be computed using an error-prone strings comparisons it
is better to provide a variable everywhere, so that we don't have the
risk of comparing values that are always false.
