[PATCH 21/36] dix: pixmap sharing infrastructure (v2)

From: Dave Airlie <airlied at redhat.com>
This is a hooks for pixmap sharing and tracking.
The pixmap sharing ones get an integer handle for the pixmap
and use a handle to be the backing for a pixmap.
The tracker interface is to be used when a GPU needs to
track pixmaps to be updated for another GPU.
v2: pass slave to sharing so it can use it to work out driver.
