Instead of the stub winsys being a special case set of #ifdef'd code used when COGL_HAS_FULL_WINSYS wasn't defined, the stub winsys now implements a CoglWinsysVtable like all other winsys backends (it's just that everything is a NOP). This way we can get rid of the COGL_HAS_FULL_WINSYS define and also the stub winsys can be runtime selected whereas before it was incompatible with all other winsys backends.
