Browse source 
* spot/twaalgos/sccinfo.hh, spot/twaalgos/sccinfo.cc: Add an optional
argument to abort on accepting SCC, to not keep track of SCC states,
and some one_accepting_scc() method.
* NEWS: Mention it.

- Rename three methods of spot::scc_info. New names are clearer. The
old names have been deprecated.
- scc_info now takes an optional argument to disable some feature
that are expansive and not always necessary. By default scc_info
tracks the list of all states that belong to an SCC (you may now
ask it not to), tracks the successor SCCs of each SCC (that can
but turned off), and explores all SCCs of the automaton (you may
request to stop on the first SCC that is found accepting).
- The new function scc_info::states_on_acc_cycle_of() is able to
return all states visited by any accepting cycles of the
specified SCC. It must only be called on automata with a
