Reverts commit c73e20628a.
This caused a regression in the GLES2 renderer because `egl->exts.EXT_device_drm` is set in
`egl_init_display()`, which is invoked after `get_egl_device_from_drm_fd()`. So the function will
always return `EGL_NO_DEVICE_EXT`.
This is needed for compositors that want to reserve space for
XWayland panels. Such a feature can be useful in a "transitional"
setup, where only the X11 window manager and compositor is replaced
but other components of an X11 desktop environment are still used.
This change simply reads the X11 property; the compositor is free
to ignore it. Thus, compositors that don't want to support such a
"transitional" feature are not impacted.
v2: Update xwayland_surface_associate()
The #sway-devel channel is now for Sway development only. #wlroots
is the new channel to use for wlroots.
We were using #sway-devel mostly for histerical raisins. Nowadays
many wlroots developers are not working on Sway.

options->scanout_primary_output indicates an output on which scanout is desirable.
Set the missing SCANOUT flag.
Fixes: 0c966f102c ("linux-dmabuf-v1: add wlr_linux_dmabuf_feedback_v1_init_with_options()")
This patch allows surfaces without keyboard focus
but with pointer focus to receive valid tokens.
This can be relevant for applications using an older version of
the layershell protocol which only provided the choice between
no keyboard focus and exclusive keyboard focus.
Instead of destroying all seats, destroy a single one. We only need
to destroy all seats at one call-site (backend_destroy), but we'll
need to destroy a single seat elsewhere in the next commit.
The hardcoded fallback "/usr/share/hwdata/pnp.ids" was only a
temporary solution to get things working while distributions were
still working on shipping it.
During a modeset, the core wlr_output logic will allocate a buffer
with a new size and commit it. However if we still have a frame
callback pending we'd refuse to perform the commit. This is
inconsistent with the DRM backend, which performs a blocking
modeset.
This is visible when resizing the Wayland toplevel. The logs are
filled with "Skipping buffer swap", and the wlr_damage_ring's
bounds are not properly updated.
Fix this by destroying the pending frame wl_callback.
In output_ensure_buffer() we create a swapchain and attach an empty
buffer to the output if necessary. We do that during the first commit.
This is fine when the first commit enables the output, however this breaks
when the first commit disables the output. A commit which disables an
output and has a buffer attached is invalid (see output_basic_test()), and
makes the DRM backend crash:

Fixes: 3be6658ee7 ("output: allocate swapchain on first commit")
Closes: https://github.com/swaywm/sway/issues/7373
Because wl_buffer.release is per-buffer and not per-commit, the
Wayland backend might create multiple struct wlr_wl_buffer per
struct wlr_buffer. As a result, the wlr_buffer_unlock() call inside
destroy_wl_buffer() can cause another struct wlr_wl_buffer to be
destroyed.
In backend_destroy() we were iterating the list of buffers with
wl_list_for_each_safe(), which is actually not safe in this case:
the next buffer is cached, but might be destroyed as a side-effect
of calling destroy_wl_buffer().
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3572
wlr_xcursor_get_resize_name() returns cursor-spec [1] based names
but the default cursor icons shipped in include/xcursor/cursor_data.h
use traditional X cursor names instead.
Compositors that use wlr_xcursor_get_resize_name() to resolve an edge
to a cursor icon name may thus be unable to render appropriate cursor
icons for users that don't have a cursor-spec compliant cursor theme
installed on their system or have it installed in an unusual place.
This patch adds cursor-spec cursor icon name aliases.

When a client attaches a NULL buffer to its wl_surface, it's
unmapped. This resets the xdg_surface in its initial state. An
extra NULL commit makes the compositor send an initial configure
event.
Note, wlr_xdg_toplevel.added is separate from wlr_xdg_surface.added.

Since 1d581656c7 ("backend/drm: set "max bpc" to the max") we
set the "max bpc" property to the maximum value. The kernel driver
is supposed to clamp this value depending on hardware capabilities.
All kernel drivers lower the value depending on the GPU capabilities.
However, none of the drivers lower the value depending on the DP-MST
link capabilities. Thus, enabling a 4k@60Hz mode can fail on some
DP-MST setups due to the "max bpc" property.
Additionally, it's not a good idea to unconditionally set "max bpc"
to the max. A high bpc consumes more lanes and more clock speed,
which means higher power consumption and the busy lanes cannot be
used for something else (e.g. other data transfers on a USB-C cable).
For now, let's tie the "max bpc" to the pixel format of the buffer.
Introduce a heuristic to make "high bit-depth buffer" a synonym of
"I want the best quality".
This is not perfect: a "max bpc" higher than 8 might be desirable
for pixel formats with a color depth of 8 bits, for instance when
the color management KMS properties are used. But we don't really
support that yet, so let's leave this for later.
