Add extension clCreateBufferFromFdINTEL to create cl buffer by external buffer object's fd.
Before this patch, Beignet can only create cl buffer from external bo by its handle using clCreateBufferFromLibvaIntel. Render node is the first choice of accessing gpu in currect Beignet implementation. DRM_IOCTL_GEM_OPEN is used by clCreateBufferFromLibvaIntel but forbidden in Render node mode. So it's necessary to add this extension to support buffer sharing between different libraries. v2: Seperate clCreateMemObjectFromFdIntel into two extensions: clCreateBufferFromFdINTEL and clCreateImageFromFdINTEL. v3: Fix rebase conflict: add a parameter when invoke cl_mem_allocate.
