twaalgos: Implement dt*a_sat_minimize_incr(...) functions
* python/spot/__init__.py: Add 'incr' boolean argument. * spot/twaalgos/dtbasat.cc: Implement dtba_sat_minimize_incr(...). * spot/twaalgos/dtbasat.hh: Declare it. * spot/twaalgos/dtwasat.cc: Implement dtwa_sat_minimize_incr(...) and deal with options. * spot/twaalgos/dtwasat.hh: Declare it. * spot/twaalgos/postproc.cc: Add option --sat-minimize=incr. * spot/twaalgos/postproc.hh: Add incr parameter. * tests/core/satmin.test: Add tests for incremental version. Update expected result. * tests/core/satmin2.test: Add tests for incremental version. * tests/python/satmin.py: Add tests for incremental version.
