twaalgos/cobuchi: Add nsa_to_nca()

Browse source 
* NEWS: Update.
* spot/twaalgos/cobuchi.hh: Declare to_dca() and nsa_to_nca().
* spot/twaalgos/cobuchi.cc: Implement them.
* python/spot/impl.i: Include new file for python bindings.
* spot/twaalgos/Makefile.am: Add new file.
* bin/autfilt.cc: Add --dca command line option. This option does not
return a deterministic automaton yet, but it will.
* tests/core/dca.test: Add tests for Büchi automata.
* tests/python/dca.py: Add a python script that builds a nondet. Streett
automaton.
* tests/python/dca.test: Add tests for Streett automata.
* tests/Makefile.am: Add all tests.

specified SCC. It must only be called on automata with a
Streett-like acceptance condition.
- The new function nsa_to_nca() is able to convert when possible an
automaton with a Streett-like acceptance to an equivalent
automaton with a co-Büchi acceptance. Actually the resulting
automaton will always recognize at least the same language. It can
recognize more if the original language can not be expressed with
a co-Büchi acceptance condition.
Deprecation notices:
(These functions still work but compilers emit warnings.)
