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.
