[Mesa-dev] r600g,radeonsi: ARB_query_buffer_object grunt work

[Edward O'Callaghan]

These two patches provide just the grunt work for ARB_query_buffer_object
support. My incomplete hardware specific callback has been left out of
this series. However this does allow a user to fake the PIPE_CAP and not
just get a segfault from a unchecked derefenced to a NULL pointer from
within 'st_StoreQueryResult()'.

Edward O'Callaghan (2):
  radeon: Provision a query_ops callback,
  radeon: Implement the get_query_result_resource() call-in
