* src/dstarparse/dstarparse.yy, src/dstarparse/dstarscan.ll
src/dstarparse/parsedecl.hh, src/dstarparse/public.hh:
Adjust to return the same return types as parse_aut.
* src/dstarparse/fmterror.cc: Delete, we can use
the one of parse_aut.
* src/dstarparse/Makefile.am: Adjust.
* src/tests/ikwiad.cc, src/bin/dstar2tgba.cc,
src/bin/ltldo.cc: Adjust usage.
* src/bin/ltlcross.cc: The the result of dstar_parse() as-is, now that
it is a TωA like those produced by parse_aut(). As a consequence,
get rid of all the code storing statistics about the input
automaton.
* src/tests/ltlcross3.test, src/tests/ltl2dstar.test: Adjust expected
CSV output.
* doc/org/ltlcross.org, src/bin/man/ltlcross.x: Adjust to not
mention that %D performs a tranformation to Büchi.
