graph: store the source indices in the transition vector

Browse source 
... and use it to sort transitions.

* src/graph/graph.hh: Adjust storage of source index.  Provide
remove_dead_transitions_(), sort_transitions_() and
chain_transitions_() methods.
* src/tgba/tgbagraph.cc (merge_transitions): Rewrite using
above methods.
* src/tgba/tgbagraph.hh: Add a comparison operator for
transitions.
* src/tgbatest/degenlskip.test, src/tgbatest/det.test,
src/tgbatest/ltl2ta.test, src/tgbatest/neverclaimread.test,
src/tgbatest/readsave.test: Adjust expected transition order in test
cases.
