render/allocator/gbm: add _with_drm_fd to create function name
...
Reserve wlr_gbm_allocator_create() for a potential future function
which takes an already-existing gbm_device as input.

render/allocator: log message when GBM is disabled
...
When the backend and renderer would need GBM but it's disabled at
compile-time, log a message to make this situation easier to debug.

Use struct initializers instead of memset()

This is a bit more type-safe.

allocator: only use DRM auth if we are master
...
Legacy DRM auth will only work if we are DRM master. Keep using an
unauthenticated DRM FD if we are not DRM master. This should be
enough for GBM.

Remove remaining wl_signal_emit calls
...
Replace them with wlr_signal_emit_safe, which correctly handles
cases where a listener removes another listener.

build: make GBM optional
...
Now that the DRM backend no longer depends on GBM, we can make it
optional. The GLES2 renderer still depends on it because of our EGL
device selection.
This is useful for compositors with their own renderers, and for
compositors using the Vulkan renderer.

render/allocator: fallback to renderer DRM FD in autocreate
...
If the backend doesn't have a DRM FD, fallback to the renderer's.
This accomodates for the situation where the headless backend hasn't
picked a DRM FD in particular, but the renderer has picked one.

render/allocator: use empty DRM lease to re-open node

render/allocator: use render node if available in reopen_drm_node
...
If we aren't trying to create a dumb buffer allocator, and if the
DRM device has a render node (ie, not a split render/display SoC),
then we can use the render node instead of the primary node. This
should allow wlroots to run under seatd when the current user
doesn't have the permission to open primary nodes (logind has a
quirk to allow physically logged in users to open primary nodes).

render/allocator: re-open GBM FD

Using the same DRM file description for the DRM backend and for the
GBM allocator will result in GEM handle ref'counting issues [1].
Re-open the DRM FD to fix these issues.
