* src/tgbaalgos/dtbasat.cc, src/tgbaalgos/dtbasat.hh:
Rename dba_sat_minimize to dtba_sat_minimize.
Make it possible to produce state-based automata, and do
not output useless clauses.
* src/tgbaalgos/dtgbasat.cc, src/tgbaalgos/dtgbasat.hh:
likewise, but also add the possibility to set the
target number of states, as in dtba_sat_minimize.
* src/tgbaalgos/postproc.cc, src/tgbaalgos/postproc.hh:
Add new options for state-based computations and
setting acceptance and states number when using
dtgba_sat_minimize().
* src/tgbatest/ltl2tgba.cc: Adjust calls to
dtba_sat_minimize().
* src/tgbatest/satmin.test: Adjust calls.
