This reverts an attempt at saving texture memory that was introduced
recently in 16fa2100. It was misguided because the same texture may be
needed in the next frame if a window has multiple previews visible on
screen at once (gnome-shell's overview). Keeping the mipmaps around
seems to reduce the peak render times of the overview by roughly 5%-10%.

Although its atomic KMS support seems to work at first, mode sets to
anything other than the Xilinx preferred max resolution of 2048x1280
would result in a hang. The xlnx kernel driver is given:
`DRM_MODE_ATOMIC_ALLOW_MODESET | DRM_MODE_PAGE_FLIP_EVENT`
and it does complete the mode set without error, but page flip events
never arrive and so you're frozen on the first frame.
Revert to legacy KMS which has no such problem with non-default modes.

If the token ended up consumed and freed, we might leave a dangling
destroy listener after freeing the token struct.
Fixes: ed516dde89 (wayland: Add destruction listener to activation token surface)
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2594>
The "activate" and "deactivate" signals on ClutterStage are used by
Cally to track the key-focus when the user is interacting with shell UI.
key-focus only gets tracked while the stage is activated.
Wayland has no concept of the stage receiving focus or not, so right now
the activation state is bound to whether there's a focus_window in
meta_display_sync_wayland_input_focus(). Since display->focus_window is
set pretty much all the time, this effectively binds activation state to
whether the stage holds a grab or not. This is almost good enough, but
it misses cases where key-focus is on the stage without a grab, for
example when keyboard-navigating the panel after using Ctrl+Alt+Tab.
It seems to make more sense to bind the activation state to whether
key-focus is set to an actor or to NULL, so let's do that instead.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2329>
In the timespan between an activation token being created and the
token being used by the activated application, the surface that started
the activation request may end up destroyed/disposed.
In that case, the token would be left with a stale surface pointer,
maybe causing crashes later on. Set up a destroy notification listener
so that we do know to unset the token surface if that situation arises,
this will result in Mutter not considering the token activatable, thus
maybe issuing the "Application needs attention" notification if the
activated surface did not immediately get focus. In any case this is
better than a compositor crash.
A typical situation where this may happen is "Open With..." dialogs,
since those don't live long after launching the application.

There is some surface tracking going on here, and all notify handlers
are possibly leaving the linked wl_listener behind. Ensure it is unlinked
in all destroy notification functions.

Since commit 1bf70334 "tests/runner: Make test runner use the headless
backend", tests are run with the native backend in headless mode, which
will attempt to open each GPU and show a warning (fatal during tests)
if it cannot.
However, in headless mode we might not be logged in on any seat (for
example we might be logged in via ssh instead), which means we might
legitimately not have permission to use any GPUs, even if they exist.
Downgrade the warning to a debug message in this case.

The catch option makes test run via 'catch'[1], which will log
backtraces whenever an abort or segmentation fault happens in any of the
subprocesses. The aim is to enable this when running in CI to help
debugging crashes that only tend to happen in CI.
While it's possible to wrap the whole meson command in 'catch', doing so
doesn't cover the KVM tests, so this option is added instead that covers
both cases.

Until recently, mutter-test-runner called into libraries that
indirectly depend on (mutter's fork of) Clutter, but did not actually
call into Clutter itself. Commit 1bf70334 "tests/runner: Make test
runner use the headless backend" gave it a direct call into Clutter,
which means the runtime linker will fail unless the executable's
RUNPATH is sufficient to find Clutter.
For future-proofing, do the same for the other test executables.

This adds the 4 new connector types that mutter didn't know about from
drm_mode.h in the kernel.
Noticed because mutter kept crashing when plugging in a USB-C adapter to
use an external monitor.

When we e.g. generate switch configs (i.e. the ones from pressing the
Super+P or the switch-config key on laptops), try a bit harder to find a
"good" monitor scale.
With "good", it means pick a scale that was used in a previous
configuration. In practice, this means that if you for example have
configured your external monitor to use a specific scale, then pressed
e.g. "built in only", and then switched back to e.g. "external only" or
"linear", the generated configuration will use the scale that was
previously configured.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2479>
If two modes are roughly the same, they should probably use the same UI
scaling factor. I.e. for the same monitor, if a 4K mode was configured to
have a certain scaling factor, and we generate a new configuration with
a similar sized 4K mode, we should re-use the scale previously
configured; however if we e.g. go from a 4K mode to a FHD mode, we
shouldn't.
This allows implementing better hueristics when using the switch-config
feature, where we'd be less likely to loose the for a certain monitor
mode combination previously configured scaling factor.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2479>
This will eventually help with better hueristics for finding a good
scale. It currently doesn't change much, but the helper will later gain
more functionality that will also help when coming up with mirroring
configs.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2479>
The resulting logical monitor was eventually marked as primary anyway,
but without the config being marked as such, various primary properties
was not set e.g. the one on the MetaOutput. Also, tests would fail.
