intel: Add support for userptr objects
Allow userptr objects to be created and used via libdrm_intel.
At the moment tiling and mapping to GTT aperture is not supported
due hardware limitations across different generations and uncertainty
about its usefulness.
v2: Improved error handling in feature detection per review comments.
v3: Rebase on top of the drm_public addition, minor whitespace addition.
