backend/drm: fix modifiers for cursor plane buffers
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.

f17b0f975d backend/drm: add wlr_drm_connector_get_id
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.

cb6f584496 backend/drm: add support for the subconnector property
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.

backend/drm: fix segfault in page_flip_handler
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.

Closes: https://github.com/swaywm/wlroots/issues/2634

91cb0fc443 backend/drm: only keep track of local buffer
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.

adfb7cd35a backend/drm: stash pending page-flip CRTC
wlr_drm_connector.crtc may be updated by the DRM backend while a
page-flip is pending. In this case, the page-flip handler won't be able
to find the right wlr_drm_connector from the CRTC ID.

Save the CRTC when performing a page-flip to ensure we always find the
right connector when we get the event.

bec1e6b149 backend/drm: remove special linear case for cursor plane
We now properly mark the cursor plane's formats as linear-only, and we
now have a version of wlr_drm_format_intersect that handles the case of
linear-only formats and implicit modifiers.

We can remove the special drm_plane_init_surface flag we had for cursor
planes. This also allows us to use a non-linear layout for cursor planes
on drivers that support it.

Tested on amdgpu GFX9.

7ea0e9f277 backend/drm: force LINEAR for cursor plane formats

FBs to have a LINEAR layout. See [1] for expectations for framebuffers

019ffe8a5b backend/drm: introduce wlr_drm_connector.name
The DRM backend is a little special when it comes to wlr_outputs: the
wlr_drm_connectors are long-lived and are created even when no screen is
connected.

A wlr_drm_connector only advertises a wlr_output to the compositor when
a screen is connected. As such, most of wlr_output's state is invalid
when the connector is disconnected.

We want to stop using wlr_output state on disconnected connectors.
Introduce wlr_drm_connector.name which is always valid regardless of the
connector status to avoid reading wlr_output.name when disconnected.

93cd3a79b2 backend/drm: stop using GBM flags
gbm_bo_create_with_modifiers doesn't take GBM flags, so our
wlr_gbm_allocator interface doesn't either. We were still internally
using GBM flags in the DRM backend, leading to awkward back-and-forth
conversions.

The only flag passed to drm_plane_init_surface was GBM_BO_USE_LINEAR, so
turn that into a bool to make sure other flags can't be passed in.

Move the "force linear" logic out of init_drm_surface, because the
supplied wlr_drm_format should already contain that information.

8bc5a92a98 Revert "backend/drm: stop force-probing connectors"
This reverts commit 713c1661b7.

It turns out we do need to force-probe on startup and on hotplug [1].
This is unfortunate, but that's just how the uAPI works. Fixing this
would require patching the kernel.

713c1661b7 backend/drm: stop force-probing connectors
After discussing with Pekka and Daniel on #dri-devel, we concluded [1]
that user-space shouldn't need to force-probe connectors. Force-probing
can take some time, so using drmModeGetConnectorCurrent can result in
faster start-up.

Users can manually trigger a force-probe if necessary:

    echo detect | sudo tee /sys/class/drm/card0-DP-1/status

Or just by running a tool like drm_info.

A similar change has been submitted to Weston [2].

fb3bea8014 backend/drm: Use legacy gamma size for legacy backend
We would always return the GAMMA_LUT_SIZE property if available, and

ee43ef3c9d backend/drm: fix "a page-flip is already pending" errors on modeset
When performing a modeset, the DRM backend will request a page-flip
event. However frame_pending wasn't set to true, so any subsequent
wlr_output_schedule_frame calls would imemdiately trigger a synthetic
frame event, asking the compositor to submit a new frame. Committing the
new frame fails with "a page-flip is already pending" error in the DRM
backend.
