Introduce apply_output_configs, which applies the specified matched
output configs as a single backend commit.
Reimplement apply_output_config_to_outputs using apply_output_configs.
Applying an output config has two stages: Atomic application of
wlr_output_state, and applicaiton of non-atomic state like output
layout.
Split the latter out into finalize_output_config for use in a later
commit.
If we can't create the XKB keymap used for keysym translation,
gracefully error out instead of crashing. This can happen if the
XKB_DEFAULT_LAYOUT is set to an invalid value, for instance.

My code archaeology isn't good enough to determine what this is here
for, but it isn't correct. We should be able to move containers in a
direction without focusing them. AFAICT i3 doesn't do this, so we
shouldn't either.
This fixes ipc commands like move <dir> with criteria that apply to
containers which are not the current focus.
i3 has had this property for over a decade but it wasn't documented
until a couple of years ago, so it was likely missed when developing
sway. Add the property to get us closer to ipc parity with i3.
Check if the app that requested a token has provided a valid input
serial and a focused surface. Downgrade activation request to urgency
otherwise.
This is mostly in line with what other Wayland compositors decided to
do, and offers a better security than the original logic.
We tried to synchronize layer shell popups with the parent layer shell
on commits, but this is subtly wrong because we would only update
the position for one layer shell that was committed, but not any other
layer that might be affected. By moving handling to the scene descriptor
we can iterate all popups and ensure they are synchronized.
This doesn't catch the error if a background changing command is
executed via swaymsg, but improves logging.
The additional checks at least propagate if e.g. forking failed.

Add a NULL check in `find_mapped_layer_by_client` like the one in `arrange_surface`.
7e69a7076f ("Drop wl_drm") has dropped wl_drm, however a lot of
software wasn't quite ready for this (Xwayland, libva, amdvlk).
Keep wl_drm disabled by default to pressure the wl_drm phase-out,
but add a -Dlegacy-wl-drm flag for users to restore the previous
behavior in the meantime.
