Introduce scc_filter_states().

Browse source 
The main motivation is the upcoming patch that introduces
simulation_sba() and requires this function.

* src/tgbaalgos/sccfilter.hh, src/tgbaalgos/sccfilter.cc: Implement it.
* src/tgbaalgos/postproc.cc: Use it for monitors, because we do not
care about acceptance conditions.
* NEWS: Mention it.
