Provide a way to output automata with state-based acceptance. Also
print the guards using to_lbt_string() for consistency: as a
consequence, atomic proposition that do not match p[0-9]+ are now
double-quoted.
* src/tgbaalgos/lbtt.hh (lbtt_reachable): Add a sba option.
* src/tgbaalgos/lbtt.cc: Implement it, and use to_lbt_string().
* src/ltlvisit/lbt.cc (is_pnum): Reject 'p' without number.
* src/bin/ltl2tgba.cc: Activate the sba option of --ba was given.
Add an option --lbtt=t to get the old behavior.
* src/bin/man/ltl2tgba.x: Document the LBTT format we use with
some links and examples.
* src/tgbatest/lbttparse.test: More tests.
* src/tgbatest/ltlcross2.test: Add a check with --lbtt --ba.
* NEWS: Update.
* src/bin/spot-x.cc, src/bin/man/spot-x.x: New files.
* src/bin/Makefile.am, src/bin/man/Makefile.am: Adjust.
* src/bin/man/ltl2tgba.x: Remove all fine-tuning options,
and make a reference spot spot-x (7).
* src/bin/common_setup.hh, src/bin/common_setup.cc: Add
a misc_argp_hidden version of the option, so that --help
and --version are not shown in the --help output used
by help2man to generate spot-x.7.
* src/bin/ltl2tgba.cc: Refer to spot-x.7.
* src/tgbaalgos/postproc.cc, src/tgbaalgos/postproc.hh: Add a
"simul-limit" option, and add two new cases to "simul"
for the two don't care simulation
* src/bin/man/ltl2tgba.x: Mention the new options.
* src/tgbaalgos/postproc.hh, src/tgbaalgos/postproc.cc: Honor the
"simul" option in the option_map.
(do_simul, do_degen): New method to wrap the algorithms that may be
altered via option_map.
* src/bin/man/ltl2tgba.x (simul): Document this option.
* src/tgbaalgos/postproc.cc: Add an option_map parameter, and use to get
extra options to pass to the degeneralization algorithm.
* src/tgbaalgos/postproc.hh: Adjust prototype, and store Boolean
variables for degeneralize() options.
* src/bin/ltl2tgba.cc: Add a -x option to fill the option map, and pass
it to the postprocessor.
* src/bin/man/ltl2tgba.x: Document the three degeneralization options.
* src/tgbaalgos/postproc.cc, src/tgbaalgos/postproc.hh: New class to
capture the postprocessing logic.
* src/tgbaalgos/Makefile.am: Add them.
* src/bin/ltl2tgba.cc, src/bin/man/ltl2tgba.x: New files.
* src/bin/Makefile.am, src/bin/man/Makefile.am: Add them.
* src/tgbatest/spotlbtt.test: Prune the list of configurations slightly.
* src/tgbatest/spotlbtt2.test: New file.
* src/tgbatest/Makefile.am: Add it.
* bench/ltl2tgba/algorithms, bench/ltl2tgba/defs.in: Adjust to
use the new binary.
* NEWS: Update.
