- make createGraphicsAllocationFromSharedHandle and
freeGraphicsMemory more threadsafe - there was race condition
where one thread called PRIME_FD_TO_HANDLE ioctl when the other just
closed the last handle with GEM_CLOSE ioctl. This led to situation
where newly acquired handle from PRIME_FD_TO_HANDLE was already invalid
and used in exec.
- adding mutex for the time of accessing shared handles container
and ioctls (GEM_CLOSE and PRIME_FD_TO_HANDLE) resolves racing problem

- createGraphicsAllocationFromSharedHandle was not threadsafe,
instead of reusing BufferObject for a single handle when
multiple threads were creating memory objects from a single VASurface,
new BO could be created and placed in container with BOs for reuse.
This was leading to errors in ioctl calls.
- add lock for following set of operations:
1. find BufferObject with a given handle in container
2. create shared BO when not found
3. add shared BO to container
prevents creating multiple BOs for a single handle
- replace recursive mutex with regular mutex as mutex shouldn't
be locked recursively
