r300g: rebuild screen/winsys interface
This creates a cleaner winsys and drop the simple screen stuff. It makes r300g use pb_bufmgr structs. It also tries to avoid overheads from mapping too often. v5: clean warnings v6: break out of cache check on first buffer - since most likely the first busy one implies all after it are busy. v7: cleanup a bit v8-merged: drop cman for now to just get all the interface changes in first. rework to changes that happened upstream Signed-off-by: Dave Airlie <airlied@redhat.com>
