rename some listeners

To keep consistency with the rest of listeners

destroy keyboard group after unlinking listeners

Last commit addressing the issue mentioned in

unlink global listeners on destroy

Continuation of 0925fe956aeddb983875f0fd892e9049e2d8cb76

Partially revert "Line saver: LISTEN_STATIC macro"

This reverts commit 33bcd2e4ca892bb0b558660c99ed63a3dfdd9011.

We keep LISTEN_STATIC for three instances where we use it. We use
simple listeners for the rest of signals.

This is the continuation of 0925fe956aeddb983875f0fd892e9049e2d8cb76

unlink some destroy listeners

Recently wlroots was updated to assert that signals do not have listeners
attached on destroy.

This is just a preliminar work to fix dwl. At the moment dwl will trigger the
assertions at exit.

do not call waitid(2) in the signal handler when Xwayland is enabled

waitid(2) is not a async-signal-safe function acording to signal-safety(7)

We can stop doing this because wlroots!4926 allows compositors to install
signal handlers for SIGCHLD.

use wlr_xwayland_surface_has_window_type() (wlroots!4553)

manually call updatemons in powermgrsetmode()

remove binary before copying to destination

Since Linux 6.11 is possible overwrite a running executable, possibly making it
crash.

tell xwayland clients they're maximized

like we do to xdg clients when tiled state is not supported.
