Currently the GSourceList has it's own allocation plus a secondary
allocation for the GList which contains it (from GMainContext). Not only
are these a pointer chase, but they are on separate cachelines too. Without
changing the code much we can at least keep things on the same cacheline
so that the pointer chase matters less.
Since the GList becomes embedded in the GSourceList you can use a
g_queue_unlink() directly removing the link without traversing the GList
like was done before.
Furthermore, we can simplify some code with g_queue_push_tail_link()
instead of some extra branching.
This should not result in any functional changes, but will eventually
allow glib to be functional on CHERI-enabled systems such as Morello.

These functions can be used to initalize pointer-type variables rather
than a gsize. This is required to support CHERI-enabled platforms where
gsize cannot be used to store pointers. Follow-up changes will migrate
the uses of g_once_init that store pointers to the new API

Commit 0b114b26872da160126a9327503a87794a100abf accidentally made the
tests only pass on systems running in a UTC timezone, as it checked the
local timezone `%Z` format against `UTC`.
This happens to pass on all the GLib CI runners except the macOS one,
which is running under CET.
Make the formatting tests timezone-independent by running them with UTC
datetimes. There’s already a separate test for checking that `%Z` works
correctly in a non-UTC timezone (`test_z`).

POSIX allows dlclose() implementations that are no-ops,
and in such case library destructors run at application
exit rather than dlclose().
That's the case, for example, of UNIX systems with the
Musl LibC.
This way, the generated GResource code won't choke if no prototypes are found
when being built by clang-cl, which also goes the _MSC_VER >= 1500 route.
Fixes clang-cl build of generated GResources code when building the appstream
git checkout, which supported Windows recently, as the build there demands
'-Werror,-Wmissing-prototypes'.

With gcc and clang using -Wsign-conversion a related warning is generated
if code using glib 2.78.0 contains function g_assert_cmpint().
Warning is fixed by adding related casts. Related tests have been also
updated and will be also compiled with -Wsign-conversion to detect
related problems in future.
The pointer argument must not be `NULL` (though it can point to a
location which is zero/null-valued), so this should be `(not optional)`
not `(not nullable)`.
Spotted in !3577.

On FreeBSD /home is generally a symlink to /usr/home, so the relative
resolves to /usr/bin instead of /bin and `sh` can only be found in /bin
on FreeBSD. Fix this by resolving symlinks in the CWD first.
Some compilers (e.g. CHERI LLVM) warn when casting a non-intptr_t integer
type to a pointer. The GSIZE_TO_POINTER() macro thus triggers warnings
which can be silence by casting to guintptr before gpointer.
NB: This macro must not be used to create valid pointers from a integer.
