Subject: [PATCH] More state management changes: - Don't lock in
 savageDDUpdateStatte, don't call savageEmitHwStateLocked - Need to grab the
 lock for texture uploads now - New SAVAGE_NEW_CULL bit in new_state to make
 sure that culling state and   raster_primitive are not examined at the wrong
 times.
