When using Mesa and LibVA in the same process, one would like to be able bind buffers from the output of the decoder to a GL texture through an EGLImage. LibVA can reuse buffers allocated by Gbm through a file descriptor. It will then wrap it into a drm_intel_bo with drm_intel_bo_gem_create_from_prime(). The problem at the moment is that both library get a different drm_intel_bufmgr object when they call drm_intel_bufmgr_gem_init() even though they're using the same drm file descriptor. As a result, instead of manipulating the same buffer object for a given file descriptor, they get 2 different drm_intel_bo objects and 2 different refcounts, leading one of the library to get errors from the kernel on invalid BO when one of the 2 library is done with a shared buffer. This patch modifies drm_intel_bufmgr_gem_init() so, given a file descriptor, it will look for an already existing drm_intel_bufmgr using the same file descriptor and return that object.
