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
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'.

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.

If glib and PCRE2 are both built for Windows as subprojects of a parent
project, cc.links() will fail because PCRE2 hasn't been built yet when
glib is being configured:
subprojects/glib-2.78.0/meson.build:2109:20: ERROR: Dependencies must be external dependencies
609d58beea changed the detection logic to avoid cc.links() in this
case, but dd5683ce64 broke it again. PCRE2 detection could use a
broader cleanup, but for now, make the minimum change to fix this case.
use_pcre2_static_flag ends up set to false, matching the behavior of
609d58beea.
Fixes: dd5683ce64 ("meson: Allow fallback & static build of pcre subproject")
The introspection parser isn't good enough to expand the shift symbol,
which means G_TYPE_FUNDAMENTAL_MAX is evaluated as (255 << 0).
We can use the `(value)` annotation to force the symbol value in the
introspection data.
See: GNOME/gobject-introspection#473
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.
When building for CHERI with additional warning flags, implicitly
converting uintptr_t to an integer type that can't store a pointer
results in a compiler warnings. Silence two of these by adding
explicit casts.
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.
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.
