nvfx: support an unlimited number of occlusion queries
Currently on nv30/nv40 an assert will be triggered once 32 queries are
outstanding.
This violates the OpenGL/Gallium interface, which requires support for
an unlimited number of fences.
This patch fixes the problem by putting queries in a linked list and
waiting on the oldest one if allocation fails.
nVidia seems to use a similar strategy, but with 1024 instead of 32 fences.
The next patch will improve this.
