on filesystem permissions.

Simon Ser 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).

Simon Ser 4e7a8707cc 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.

GBM allocator will result in GEM handle ref'counting issues [1].
Re-open the DRM FD to fix these issues.
