Stephan Hilb 9f012cac2f drm: check for PRIME support
PRIME support for buffer sharing has become mandatory since the renderer
rewrite. Make sure we check for the appropriate capabilities in backend,
allocator and renderer.

See also #2819.

Simon Ser 4f06ce2550 render/gbm_allocator: avoid drmPrimeHandleToFD
Some drivers (e.g. nouveau) need to do some book-keeping when exporting
a BO handle to a DMA-BUF [1]. Using drmPrimeHandleToFD directly hides
the export from the user-space drivers and causes some ref'counting
issues.

So we can't properly handle BOs with a different handle for each plane
until [2] lands.

Simon Ser bf86110fc5 render/gbm_allocator: set modifier to INVALID if implicit
When gbm_bo_create is used and the GBM implementation does support
modifiers, gbm_bo_get_modifier may return something other than
DRM_FORMAT_MOD_INVALID. This can cause issues with the rest of the
stack (e.g. EGL or KMS) in case these don't support modifiers.

Instead, force the modifier to INVALID, to make sure no one uses
modifiers.

Simon Ser b5cefada92 render/gbm_allocator: export to DMA-BUF on init
Instead of lazily exporting BOs to DMA-BUFs, do it on init. This is
the only way to use the buffer, so there's no point in deferring
that work.

This is preparatory work for the next commit.

Simon Ser c73a8cde83 render/gbm_allocator: fix gbm_device use-after-free
We need to destroy any gbm_bo we've created before gbm_device_destroy.
