ephyr: Properly implement hardware cursors (v3)

When dix hands us a new cursor we proxy it through to the host server;
since we keep the host XID on the cursor bits private we can switch
among them with just ChangeWindowAttributes.

v2:
Use xcb-renderutil for argb format lookup (Uli, Keith)
Fall back to core cursors for host RENDER < 0.5 (Keith)
Drop useless ephyrEnableCursor
Consistently create/destroy the cursor image GC on both paths
Treat null cursor from dix as invisible

v3:
Initialize the invisible cursor's image (Keith)
