e2aff8a9b0 xdg-activation-v1: add data field and emit token destroy events
The data field is useful to track metadata about a token. The destroy
events are useful for compositors that track application startup to
let them know they can stop doing that.

6ad0f819e2 xdg-activation-v1: enable compositors to request their own tokens
These new functions allow a compositor to request new managed tokens
without participating in the xdg-activation procedure as a wayland
client.

This enables the compositor itself to behave as a launcher
application.

b2f6ff45c2 output: fix stack variable lifetime in wlr_output_send_present
Variables on the stack are released when the parent block is closed.
Here, `now` is used outside of the `if` block, causing the following
crash when starting Sway with the headless backend:

0817c52a21 backend/drm: get rid of BO handle table
The BO handle table exists to avoid double-closing a BO handle,
which aren't reference-counted by the kernel. But if we can
guarantee that there is only ever a single ref for each BO handle,
then we don't need the BO handle table anymore.

This is possible if we create the handle right before the ADDFB2
IOCTL, and close the handle right after. The handles are very
short-lived and we don't need to track their lifetime.

Because of multi-planar FBs, we need to be a bit careful: some
FB planes might share the same handle. But with a small check, it's
easy to avoid double-closing the same handle (which wouldn't be a
big deal anyways).

There's one gotcha though: drmModeSetCursor2 takes a BO handle as
input. Saving the handles until drmModeSetCursor2 time would require
us to track BO handle lifetimes, so we wouldn't be able to get rid
of the BO handle table. As a workaround, use drmModeGetFB to turn the
FB ID back to a BO handle, call drmModeSetCursor2 and then immediately
close the BO handle. The overhead should be minimal since these IOCTLs
are pretty cheap.

a80f2b2816 scene: inline subsurface_tree_destroy
This is only called from one function.

To destroy the wlr_scene_subsurface_tree from elsewhere, callers
can destroy the scene-graph node returned by
wlr_scene_subsurface_tree_create instead (just like a compositor
would do). subsurface_tree_handle_surface_destroy does exactly this.

Inlining avoids calling subsurface_tree_destroy by mistake.

e22a386319 Add error handling to backend creation
This commit adds two error-handling cases to the function
attempt_dmr_backend. Specifically:

- In the case where the number of found GPUs is zero, we now
  print a log message indicating this and return a NULL pointer
- In the case where we could not successfully create a backend
  on any GPU, we now log a message indicating this and return
  a NULL pointer

This allows us to provide more descriptive error messages,
as well as avoid a SEGFAULT (the function
`ensure_primary_backend_renderer_and_allocator` dereferences the pointer
given, which could be NULL until this patch) when these cases arise.

8e34692250 render/vulkan: add Vulkan renderer
This new renderer is implemented with the existing wlr_renderer API
(which is known to be sub-optimal for some operations). It's not
used by default, but users can opt-in by setting WLR_RENDERER=vulkan.

The renderer depends on VK_EXT_image_drm_format_modifier and
VK_EXT_physical_device_drm.

13cdb84ee8 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).
