parseaut: make the scanner reentrant

Browse source 
* spot/parseaut/parseaut.yy, spot/parseaut/parsedecl.hh,
spot/parseaut/public.hh, spot/parseaut/scanaut.ll: Use a reentrant
scanner, so that we can now parse multiple automaton streams at the
same time.  This is needed for the future autcross, which is going to
read several individual automata produced by different tools, while
reading the stream of automata to process.

- The automaton parser is now reentrant, making it possible to
process automata from different streams at the same time (i.e.,
using multiple spot::automaton_stream_parser instances at once).
Python:
- The 'spot.gen' package exports the functions from libspotgen.
