When GNOME shell runs on a less memory system (for example 3 GB RAM), it
is usually killed by the kernel OOM-killer easily. Because, it has a
higher OOM score. However, GNOME desktop environment cannot do anything
when the GNOME shell is killed.
This commit adjusts and lowers down gnome-shell process' OOM score to
avoid being killed by the kernel OOM-killer too early. In other words,
sacrifices other processes first.

This means the screen share window view gets updated also when the title
of a window changes. This is important since it often changes shortly
after mapping, which would otherwise go unnoticed by
xdg-desktop-portal-gnome.
An example is launching Files and it showing up as 'Loading..', or
launching a terminal, and it not showing the proper title (current
directory), but some place holder that is never visible on the
application window.
Adding it to the window tracker instead of in introspect.js itself is
for convenience - there is no per window signal tracking there, and it
already listens to the signal emissions about changed windows.

We no longer *require* a merge request URL in commit messages, we
ban them (since Marge is kind enough to add them for us).
While at it, add a small section on prefixes (~~stolen from~~
inspired by mutter).

If we are getting purpose hint changes while the language switcher is popped
up, this likely means the purpose hint was actually triggered by the key
focus change induced by the language switcher popping up.
In this case, we on one hand would like to preserve the state that applied
before thise focus change, and on the other we very much want to avoid the
keymap change that would forget about the keys being pressed.

Extensions can export asynchronous enable() and disable()
functions. To guard against re-entrancy when enabling or
disabling an extension, this commit adds two new states:
ENABLING and DISABLING which are set immediately prior
to calling enable() and disable() respectively.
This commit updates the extensions CLI and Extensions app
with new strings for these states.

When we're running in e.g. CI, or in a virtual machine without hardware
acceleration, and we actually want to enable animations despite the
potential performance implications, change the AnimationsSettings to
only inhibit if we're a XVNC instance or not hardware accelerated if
--force-animations wasn't passed.
Still inhibit animations if there is a remote desktop session that
explicitly disables animations.

If we want to run with the welcome screen showing, it should be done so
explicitly. Hide it if there is a perf test running for now, so that
what we test is what is expected to be tested.
We also don't want to show the root user warning, since we'll be running
as root in the CI containers.

This allows neat tricks like first arranging the script `fakegdb`:
```sh
function ignore_gdb_arg() {
if [[ "$1" == "--quiet" ]] || [[ "$1" == "--args" ]]; then
return 1
else
return 0
fi
}
ignore_gdb_arg "$1" || shift
ignore_gdb_arg "$1" || shift
echo exec "$@"
```
then running
```sh
meson test -C build -v perf-basic --test-args '--wrap "gdb --args"' --gdb --gdb-path `which fakegdb`
```
To make it possible to run the perf test case with gdb running the
actual gnome-shell.

This test runs all of GNOME Shell using the headless backend inside a
mocked D-Bus environment. The basic test tests, well, basic things, like
the panel menu, the overview, showing the app grid view, as well as
going back to the session view.

If one wants to run tests the non-installed gnome-shell, that currently
fails as gnome-shell the executable attempts to link against
./build/src/libgnome-shell.so, but when GObject introspection tries to
find what library to link to for Shell, it goes to the installed
libgnome-shell.so, causing two different versions of libgnome-shell.so
to be loaded.
This, however, can be avoided thanks to meson adding $ORIGIN paths to
relevant libraries before installing an executable. What this means in
practice is that we can inspect ourself upon startup, discover whether
the RPATH/RUNPATH header contains $ORIGIN, and if so, expand it to the
directory containing the executable, and prepend the introspection
search paths with said directory.
This effectively means that the introspection machinery now finds the
same library that the linker linked the gnome-shell executable with,
making it run successfully.
It's not possible to use $GI_TYPELIB_PATH since
g_irepository_prepend_library_path() takes precedence. There is no
"append" variant of that API.

Tearing down gjs means that we won't have any dangling references kept
alive by GC or otherwise alive Javascript objects, when we finally tear
down the mutter context. This allows for a clean shutdown of GNOME
Shell.

Move back actors that were adopted from mutter (window_group,
top_window_group, the feedback group) from the uiGroup to the stage, and
then destroy the uiGroup. This will tear down more or less all of GNOME
Shells actors gracefully.

The nPages property can be 0, which is the case in a stripped down CI
image without a single app to be listed, which means we can't clamp to
`nPages - 1`, since that'll give us a negative index and the following

Running dispose on the setting causes issues when we're being destroyed,
as the signal handler in the GSettings binding will be cleared by the
GObject itself before it has the chance, resulting in warnings.

With meta_exit() we bypass the tear down procedures, making the test
case excercising much less code paths. Use meta_context_terminate()
instead, as that exits the main loop and goes through proper shutdown.
