postproc: introduce dba-simul, and have simul=0 disable all *-simul

Browse source 
* spot/twaalgos/postproc.cc, spot/twaalgos/postproc.hh: Implement the
dba-simul option, and disable ba-simul, dba-simul, dpa-simul,
det-simul when simul=0.
* bin/ltlsynt.cc: Adjust.
* bin/spot-x.cc: Document dba-simul and adjust other variables.
* tests/core/minusx.test: Add some test.
