Robert Noland f00755f06b Rework memory allocation to allocate memory with different type names. This
will ease the identification of memory leaks as the OS will be able to track
allocations for us by malloc type.  vmstat -m will show all of the
allocations.

Convert the calls to drm_alloc() and friends, which are used in shared code
to static __inline__ while we are here.
