Across a wayland compositor, there are multiple shells: It can be
a toplevel, or a layer_shell, or even something more meta like a drag
icon or highlight indicators when dragging windows around.
This object lets us store values that represent these modes of operation
and keep track of what object is being represented.
Since output layout is destroyed when the wayland display is destroyed
we run into a destroy listener order problem: Either the display starts
destroying the outputs first, in which case we're good: The existing
handling will clean up. However, things go wrong if the display decides
to destroy the output layout first. In this case, sway will hold
invalid references to the output layout as part of each output so that
when it finally goes to destroy them, sway will dereference destroyed
output layout bits.

`gcc-14` added a new warning around dangerous use of `strncpy()` withi
known overflow:
../sway/config.c: In function 'do_var_replacement':
../sway/config.c:983:33: error: '__builtin___strncpy_chk' specified bound depends on the length of the source argument [-Werror=stringop-truncation]
983 | strncpy(newptr, var->value, vvlen);
| ^
../sway/config.c:971:45: note: length computed here
971 | int vvlen = strlen(var->value);
| ^~~~~~~~~~~~~~~~~~
It's a bit fishy to rely on truncating behaviour of `strncpy()`. The
change uses `memcpy()` as more explicit way to express copy of `vvlen`
bytes.
Remove any existing executed criteria items at unmap time. If a window
gets unmapped but not destroyed, we want to reapply 'for_window'
criteria. Fixes#6905.
This reverts commit afde6369
"seat: avoid unneeded reloading xcursor theme".
Always avoiding to reload the xcursor theme prevents reloading the
cursor even when this is desired. Instead seat_configure_xcursor
can determine whether a full reload is necessary.
To stay with the spirit of the reverted change, cursors are only fully
reloaded, if the theme has changed.
Fixes#6931
`gcc-14` added a new `-Walloc-size` warning that makes sure that size of
an individual element matches size of a pointed type:
https://gcc.gnu.org/PR71219
`sway` triggers it on `calloc()` calls where member size is used as
`1` (instead of member count):
swaynag/config.c:169:65: error: allocation of insufficient size '1'
for type 'struct swaynag_button' with size '48' [-Werror=alloc-size]
169 | struct swaynag_button *button = calloc(sizeof(struct swaynag_button), 1);
