Initial implementation for DRI3 v1.1. Only the DRI3 implementation
is there, backends need to implement the proper hooks.
Version is still set to 1.0 so clients shouldn't use the new
requests yet.
v2: Use depth/bpp instead of DRM formats in requests
v3: Remove DMA fence requests from v1.1
Add screen/drawable modifier sets
v4: Free array returned by 'get_drawable_modifiers()'
v5: Fix FD leak
