It turns out wl_event_source_check is not enough to guarantee that the
remote wl_display will be flushed after we queue requests. We need to
explicitly flush, just like we do in our X11 code.

When we receive an Expose event, that means that we must redraw that
region of the X11 window. Keep track of these regions with pixman
regions, and merge them with the additional output damaged regions.
Fixes#2670
The region variable was shadowed in an if block. As a result, in the
outer block region was always XCB_NONE and was never destroyed (causing
a memory leak on the server).

This actually simplifies the logic since we no longer have to wait for
enter/leave events, and also improves the UX when e.g. handling a crash
with gdb attached.

In 93cd3a79b2 ("backend/drm: stop using GBM flags"), we stopped
using the GBM_BO_USE_LINEAR flag in favor of a modifier list set
to { DRM_FORMAT_MOD_LINEAR }. However, the last argument of
drm_plane_init_surface disables modifiers -- so the buffer will just
get allocated with an implicit modifier, without necessarily being
LINEAR.
To fix this, allow modifiers when allocating the cursor buffers.
wlr_drm_plane.formats should already have the necessary LINEAR
restrictions.

This allows a compositor to get a KMS connector object ID from a
wlr_output. The compositor can then query more information about
the connector via libdrm.
This gives more freedom to compositors and allows them to read
KMS properties that wlroots doesn't know about. For instance,
they could read the EDID or the suggested_{X,Y} properties and
change their output configuration based on that.
The subconnector property indicates the connector sub-type. This is
useful because that usually indicates what kind of connector the user
has plugged in to their monitor, e.g. a DisplayPort-to-DVI cable will
indicate a DVI subconnector. Also some laptops have non-DP connectors
that are internally linked to a DP port on the GPU.
Set the output description accordingly.

The new wlr_renderer_autocreate API is great for compositors, however
it causes some issues with DRM multi-GPU support.
A DRM child backend wants the compositor to use the parent GPU, so it
exposes the parent's DRM FD in get_drm_fd. However, in order to be able
to perform multi-GPU buffer copies, the child DRM backend still needs to
create a local renderer.
Use the new private wlr_renderer_autocreate_with_drm_fd function to
avoid creating a renderer for the parent GPU.
Fixes: e128e6c08d ("render: drop egl parameters from wlr_renderer_autocreate")
Instead of requiring callers to manually make the EGL context current
before binding a buffer and unsetting it after unbinding a buffer, do
it inside wlr_renderer_bind_buffer.
This hides renderer-specific implementation details inside the
wlr_renderer interface. Non-GLES2 renderers may not use EGL.
This removes all EGL dependencies from the backends.

Since 5b1b43c68c ("backend/drm: make wlr_drm_plane.{pending,queued,current}_fb
pointers"), current_fb can be NULL if there's no buffer. If current_fb
is not NULL, current_fb->wlr_buf is guaranteed to not be NULL.

Stop using wlr_drm_surface.{width,height} to figure out the size of a
gbm_bo. In the future we'll stop using wlr_drm_plane.surf, so these will
be zero. Instead, rely on gbm_bo_get_{width,height}.
Stop keeping track of buffers on the parent GPU when multi-GPU is used.
This removes support for export_dmabuf on secondary GPUs, but renderer
v6 will bring this back by managing the swapchains in wlr_output instead
of the backends.
