There are some flavors of MIPS ABIs, such like r6 vs legacy,
nan2008 vs nan1985 etc.
The `cc -r` may not produce the correct elf binaries.
So let's skip this test for MIPS.
The C standard does not specify whether the underlying type of an enum
is signed or unsigned, and until C23 there was no way to control this
explicitly. GCC appears to make enums unsigned unless there is a
negative value among cases of the enum, in which case it becomes signed.
MSCV appears to make enums signed by default.
A bitfield of an enum type (which is not specificied in the C standard
either) behaves as if it was an instance of a numeric type with a
reduced value range. Specifically, a 'signed int val : 2;' bitfield will
have the possible values of -2, -1, 0, and 1, with the usual wraparound
behavior for the values that don't fit (although this too is
implementation-defined).
This causes the following issue, if we have:
typedef enum
{
G_ZERO,
G_ONE,
G_TWO
} GFoo;
struct _GBar
{
GFoo foo : 2;
};
and then assign bar.foo = G_TWO and read it back, it will have the
expected value of 2 (aka G_TWO) on GCC, but a value of -2 (not matching
any of the enum variants) on MSVC.
There does not seem to be any way to influence signedness of an enum
prior to C23, nor is there a 'unsigned GFoo foo : 2;' syntax. The only
remaining options seems to be never using enums in bitfields, which is
what this change implements.
This corresponds to https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/6467
in GTK.

This triggered a warning from the CHERI compiler since the struct contains
a `void *` but `__attribute__((aligned(8))` reduced alignment to less than
the `void *` alignment (which is 16 for Arm Morello).

This should not result in any functional changes, but will eventually
allow glib to be functional on CHERI-enabled systems such as Morello.

The Comment field provides a user-visible description of the app,
which usually contains generic words ("and", "or", "not", "is", ...)
that add noise when used for search.
It made some sense to match against the field as a fallback for
Keywords, before that key was well established. However that key
has been around for years now, so hopefully every app where additional
terms are helpful uses it by now.
With that, the downside of added noise outweighs the benefit, so
it's time to stop matching on comments.
When setting the file time using utimensat, don't ignore
microseconds for access/modify times. By doing that, they're preserved
when using g_file_info_set_modification_date_time and then setting the file's
attributes from it.

Commit 9e2ad88455 improved app search results by allowing to differentiate
their match_type: prefix match or substring match; while giving more priority
to prefix matches over substring matches, but only when they are in the same
match_category[1].
This was a step forward but, as outlined in #3082, still not enough to get
most relevant results first to the user, because apparently (and for the
specific case of desktop app searching) a prefix match in a lower category
is more relevant to the user than a substring match in a higher category.
So that's what this commit implements, i.e. it makes sure prefix matches
are still preferred over substring matches but this time not only when
in the same category but also across different categories.
[1] Match category is the Desktop file key where the match happened.
They are shown below from top to lesser priority.

· Add a usage output that is printed when called with no argument
or with '--help' argument. This is helpful as it avoids having
to read the source code to know how to run the different options.
· Adds new '--should-show-only' option to 'search' command, to
better mimick the gnome-shell app search, by not returning
apps with NoDisplay=true.
Example for running a desktop app search with the new option from
inside the GLib build dir:
$ gio/tests/apps search --should-show-only settings
Make sure to fail consistently in case people created a GPropertyAction
with g_object_new() without passing a property name.
Bindings that construct objects with g_object_new() have no idea if a
property is mandatory.

This avoids a critical warning from trying to disconnect a signal
handler from a `NULL` object if `paction->object` is `NULL` for whatever
reason (see: the following commit).

The `GTK_USE_PORTAL` environment variable has started to be misused by
users, which is causing deployment issues (such as portal services
themselves ending up being forced to use portals, which is never going
to work).
Try and sidestep users’ broken configurations by renaming the
environment variable, and also separating it from the old GTK
environment variable, since the GLib one affects a lot more processes.
This environment variable is meant to be used for
debugging and development, and never in production.
GTK already renamed their environment variable in
https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/4829, so keeping the
`GTK_USE_PORTAL` name in GLib doesn’t make sense anyway.

I had thought that because `g_source_destroy()` was called for the two
sources (cancel and timeout) in the `GTask` finalize function for a
threaded resolver operation, that it would be fine to use a plain
pointer in the source callbacks to point to the `GTask`.
That turns out to not be true: because the source callbacks are executed
in the GLib worker thread, and the `GTask` can be finalized in another
thread, it’s possible for a source callback (e.g. `cancelled_cb()`) to
be scheduled in the worker thread, then for the `GTask` to be finalized,
and then the source callback to continue execution and find itself
doing a use-after-free.
Fix that by using a weak ref to the `GTask` in the source callbacks,
rather than a plain pointer.

We already validated that the required headers for each type of D-Bus
message were present. However, we didn’t validate that they contained a
variant of the right type. This could lead to functions like
`g_dbus_message_get_path()` returning `NULL` unexpectedly.
This failure could only be hit when using GDBus in peer-to-peer mode, or
with a D-Bus server which didn’t validate the headers itself. The
reference D-Bus server does validate the headers, and doesn’t forward
invalid messages to clients.

Add test cases that result in lookup of the port via
getservbyname().
As the result depends on "/etc/services", it's not reliably the same on
every system. It requires a workaround.
Commit cf55c31170 added a new test which
uses `ptrace()` to check some `GSubprocess` behaviour. FreeBSD uses
different symbol names for ptrace symbols, and we haven’t tested whether
the test works (and reproduces the failure) on FreeBSD, so skip the test
for now.

The test case will fail with the
g_assert_false (g_subprocess_get_successful (proc));
assert failing. Without the fix, it'll hit sometimes, but rather
unreliably. When running `meson test --repeat 100`, it'll reproduce
anywhere between the first or much later, but mostly before the 20th
iteration on my system.
