While an index greater than `G_MAXINT` can’t be passed to
`g_ptr_array_insert()`, `-1` can be — and if that’s done with an array
which has more than `G_MAXINT` elements in it, the new element will be
inserted part-way through the array rather than being appended.
Spotted by building with `-Wsign-conversion`.

The latter only accepts a `gint` as the number of elements in the array,
which means that its use in `GArray` (and related array implementations)
truncates at least half the potential array size.
So, introduce a replacement for it which uses `size_t` for the number of
elements. This is inline with what `qsort()` (or `qsort_r()`) actually
does. Unfortunately we can’t directly use `qsort_r()` because it’s not
guaranteed to be a stable sort.
This fixes some `-Wsign-conversion` warnings (when building GLib with
that enabled).

libgirepository is not needed by most of the modules, but it is needed
by the `g-ir-scanner` generated dumper program. If we don’t explicitly
include the local version of it here, Meson will implicitly link against
it anyway, and that might pull in a different version, or try to link
against a half-built local version as the build ordering dependency tree
won’t reflect this relationship.

Commit 9dad94e7q ensured `test_data` is freed when a test is skipped,
but didn't ensure that when a whole test suite is skipped.
We are assuming the ownership of `test_data` is passed to GTestCase
with `g_test_add_data_func_full()` so free `test_data` always when
freeing a test case.

gmacros.h casts functions to GDestroyNotify, which prevents enabling the
following hardening options in applications: -fsanitize=address
-fsanitize=cfi-icall (without -fsanitize-cfi-icall-generalize-pointers),
and -Wcast-function-type-strict.
Define another inline function that warps the original function into
GDestroyNotify.

When the file name is too long (for example, more than 238 bytes on
ext4), this will cause the creation of the .trashinfo file to fail.
Let's shorten the .trashinfo filename in this case, after all the
trash specification only requires unique filenames (see
`Contents of a trash directory` section in
https://specifications.freedesktop.org/trash-spec/trashspec-latest.html).
This should test the limits of loading 4GB files on i386 platforms, such
as the Hurd CI runner. On such platforms, `sizeof(size_t) == 4`.
This should fix the compiler warning from
https://gitlab.gnome.org/GNOME/glib/-/jobs/3989442:
```
../gio/tests/file.c:2931:51: error: left shift count >= width of type [-Werror=shift-count-overflow]

They take too long to include in a normal test run. They’ll still be run
in CI once a week as part of our scheduled slow test job.

The tests - one for sync, one for async - create a sparse file for
this purpose, so this should be cheap on the fileystem.
Of course, the test still allocates >4GB of memory for the data that it
returns from g_file_load_contents(), I hope the CI test runners can deal
with that.
GByteArray is limited to 4GB in size and the current code silently
overflows when that happens.
Replace both load_contents() and load_contents_async() implementations
with a version that uses realloc() and gsize to maintain the array.
The default values for construct properties always have to be set, even
if those properties are deprecated. The code to do that is in GLib, and
not under the control of the user (unless they completely override the
`constructor` vfunc, which is not recommended). So don’t emit a warning
for that if `G_ENABLE_DIAGNOSTICS` is enabled.
In particular, this fixes deprecation warnings being emitted for
properties of a parent class when chaining up with a custom constructor,
even when none of the child class code mentions the deprecated property.

Disable tests that require update-desktop-database when it is missing.
It requires glib to build so it will be missing when bootstrapping glib.

Without the -Wno-typedef-redefinition option, clang complains if a typedef
gets redefined in gnu99 mode (since this is officially a C11 feature). This
also happened with old versions of GCC.
So, don't break the build on such warn, since we want to support
toolchains that supports C11 anyways.
We have required C99 for a while; in the meantime, most C toolchains
have moved on to C11 or later as the default C standard.
We still allow for C99 toolchains, but in the future we are going to
require a C11 toolchain to build and use GLib.
It seems to have been accidentally enabled by the switch to making
dtrace a Meson feature. This has only just been caught because the
FreeBSD CI runner has been offline for several weeks (see
https://gitlab.gnome.org/Infrastructure/Infrastructure/-/issues/1503).
With dtrace enabled, the FreeBSD CI build fails with:
```

Previously it was mapped (as a default) to `G_IO_ERROR_FAILED`.
It’s the error that macOS returns when trying to connect to a socket which
is bound but not listened to. Linux returns `ECONNREFUSED` in this case.
It’s helpful if they both map to the same `GIOError` value.
This should fix the `/socket-client/connection-fail` test on macOS,
which is currently
[failing](https://gitlab.gnome.org/GNOME/glib/-/jobs/3970547) with:
```
