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

on filesystem permissions.

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).

buffer: add data_ptr access flags
...
This allows callers to specify the operations they'll perform on
the returned data pointer. The motivations for this are:
- The upcoming Linux MAP_NOSIGBUS flag may only be usable on
read-only mappings.
- gbm_bo_map with GBM_BO_TRANSFER_READ hurts performance.

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.
