Thomas Hellstrom 4aff1013f5 drm/ttm: Add ttm lock functionality. 
This is intended to be used by ttm-aware drivers to
1) Block clients to inactive masters when
they try to validate buffers for GPU use.
2) Optionally block clients to the current master when
there is thrashing due to GPU memory shortage.

Used by the vmwgfx driver.
