winsys/svga: Update to vmwgfx kernel module 2.1

Browse source 
Introduces fence objecs and a size limit on query buffers.
The possibility to map the fifo from user-space is gone, and
replaced by an ioctl that reads the 3D capabilities.

* TODO:
*
* Fencing is currently a bit inefficient, since we need to call the
* kernel do determine a fence object signaled status if the fence is not
* signaled. This can be greatly improved upon by using the fact that the
* execbuf ioctl returns the last signaled fence seqno, as does the
* fence signaled ioctl. We should set up a ring of fence objects and
* walk through them checking for signaled status each time we receive a
* new passed fence seqno.
