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.
