This commit changes the use of `ngettext` with `g_dngettext`. The
project defined `g_dngettext` (with domain support) provides the same
functionality as `ngettext` with a NULL domain provided. The purpose of
this change is to help address a build error for certain compilers that
trigger a `format-nonliteral` error-promoted-warning when using
`ngettext` (see also [1][2]). The benefit of switching to use
`g_dngettext` is that the function is defined with `G_GNUC_FORMAT`. This
provides a hint to GNU GCC compilers to still sanity check these
arguments, but not generate a `format-nonliteral`.

This reverts commit 4ae8606b6f. The idea
for the change [1] was to address a build error for certain compilers
that trigger a `format-nonliteral` error-promoted-warning since these
compilers do not gracefully support `ngettext` usage. The changes
following a pattern from an old commit [2]; however, James Hilliard has
pointed out these changes do not work as intended. A deeper inspection
of the commit showed that the commit was from an old merge request that
was not pulled in, detailing why the changes did not work (see also
[3][4]).
Manipulating the sockets unit test confirms that the format values no
longer get a proper value:
...
ok 9 /socket/address
ok 10 /socket/unix-from-fd
ok 11 /socket/unix-connection
**
GLib-GIO:ERROR:../gio/tests/socket.c:1493:test_unix_connection_ancillary_data: assertion failed (err == NULL): Expecting one fd, but got %d
(g-io-error-quark, 0)
...
And reverting this change restores the original functionality:
...
ok 9 /socket/address
ok 10 /socket/unix-from-fd
ok 11 /socket/unix-connection
**
GLib-GIO:ERROR:../gio/tests/socket.c:1493:test_unix_connection_ancillary_data: assertion failed (err == NULL): Expecting 1 control message, got 0 (g-io-error-quark, 0)

If both __NR_futex and __NR_futex_time64 are defined, g_futex_simple()
will first call futex_time64(). If that fails with ENOSYS, then
futex_time() is called instead. However, errno was not saved and
restored in this case, which would result in g_futex_simple()
returning with errno set to ENOSYS, even if futex_time() succeeded.
These make it a bit easier to track the ongoing resolver tasks, as the
tasks and/or their closures are not tracked in a big list somewhere.

It’s a bad idea to use it without some care for how much it’s being
called in parallel, or dependencies between tasks. If the thread pool
gets exhausted by too many inter-dependent calls to
`g_task_run_in_thread()` then the process will livelock.

As with the previous commit.
The logic has to be a little contorted here to avoid leaving the context
locked after emitting the critical warning. Execution does (and should)
continue after a critical warning by default, so we should do our best
to recover.

The documentation was fairly clear before, but we can make it clearer:
it’s a programming error to call `g_main_context_release()` if you have
not received a true return value from `g_main_context_acquire()` before.

We need a way to initialise refcounted types placed in static storage,
or on the stack. Using proper macros avoids knowing the magic constant
used for grefcount and gatomicrefcount.
Update a series of error messages to use `g_set_error_literal` instead
of `g_set_error`. This should prevent `format-nonliteral` compiler
issues when `-Werror` is configured:
../gio/gunixconnection.c: In function ‘g_unix_connection_receive_fd’:
../gio/gunixconnection.c:183:9: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
183 | nscm);
| ^~~~
../gio/gunixconnection.c:217:20: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
217 | nfd);
| ^~~
../gio/gunixconnection.c: In function ‘g_unix_connection_receive_credentials’:
../gio/gunixconnection.c:601:24: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
601 | nscm);
| ^~~~
This is similar to a previous change [1] made to `gunixconnection.c`.

In non-perf mode, we were making only one thread to win the race to increase
the value, but since we're launching more threads anyways let's allow
more of them to have a chance to do something, to make the test more
valuable, even if it's still quick enough.
This removes the `comment` member of the GKeyFileGroup structure, which
seemed intended to distinguish comments just above a group from comments
above them, separated by one or more blank lines. Indeed:
* This does not seem to match any specification in the documentation,
where blank lines and lines starting with `#` are indiscriminately
considered comments. In particular, no distinction is made between the
comment above the first group and the comment at the beginning of the
file.
* This distinction was only half implemented, resulting in confusion
between comment above a group and comment at the end of the preceding
group.
Instead, the same logic is used for groups as for keys: the comment
above a group is simply the sequence of key-value pairs of the preceding
group where the key is null, starting from the bottom.
The addition of a blank line above groups when writing, involved in
bugs #104 and #2927, is kept, but:
* It is now added as a comment as soon as the group is added (since a
blank line is considered a comment), so that
`g_key_file_get_comment()` returns the correct result right away.
* It is always added if comments are not kept.
* Otherwise it is only added if the group is newly created (not present
in the original data), in order to really keep comments (existing and
not existing).
Closes: #104, #2927
Since commit c0ca3f99 this test is strictly depending on GDesktopAppInfo
that is not defined or available in macos, so skip the test as we do for
windows.
We could have done this at meson level too, but keeping it this way is
probably a better reminder that this should be adapted for such scenario
one day™

The merge request !2848 added code to automatically detect the module
prefix on macOS, with a test for the Mac #define TARGET_OS_OSX. However,
older versions of the SDK (at least 10.11) don't provide this #define,
leading to build failure. If the #define is missing, fall back to
checking TARGET_OS_MAC. On newer SDKs this symbol is also true for
watchOS, etc., but in those situations TARGET_OS_OSX is available.
Even though having NULL as nullptr should be the standard for newer C++
versions, it may break some headers, so let's not touch it for now.

A context iteration we're doing lots of lock/unlocks and that's fine to give
other threads contexts a chance to run, but we're doing it also just to call
other functions that require locking, and this can be avoided.
Other threads can still have a chance to run while releasing the ownership
of the context.
Various gio modules include gmodule.h that requires the
gmodule-visibility.h to be already built.
To make this easier, just provide a dependency and use it where we are
building modules that do not depend on libgio_dep (that already includes
that).

The generated gir file marks the size parameter as "out" by default. This is wrong in the context of a caller allocated buffer with a given size. Explicitly marking the size parameter as (in) fixes the issue.
In practice, this will never happen.
If `getcwd()` returns `ERANGE` whenever the working directory is ≥
`PATH_MAX`, though, the previous implementation of the loop would run
until `max_len == G_MAXULONG`, and would then overflow when adding `1`
to it for a nul terminator in the allocation.
Avoid that problem by always keeping `buffer_len` as a power of two, and
relying on `getcwd()` to write a nul terminator within the buffer space
it’s given. It seems to do this on all platforms we care about, because
the previous version of the code never explicitly wrote a nul terminator
anywhere.

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.
