Thomas Hellstrom 57c5ee79ac vmwgfx: Add fence events 
Add a way to send DRM events down the gpu fifo by attaching them to
fence objects. This may be useful for Xserver swapbuffer throttling and
page-flip done notifications.

Bump version to 2.2 to signal the availability of the FENCE_EVENT ioctl.

As a benefit, they help avoid stale user-space fence handles.
