Browse source 
Fixes #114.

* src/parseaut/public.hh: Add support for a trust_hoa option.
* src/parseaut/parseaut.yy: If trust_hoa is set, recognize the
"inherently-weak" and "stutter-invariant" properties.
* src/bin/common_conv.cc, src/bin/common_conv.hh (read_automaton):
Move...
* src/bin/common_hoaread.cc, src/bin/common_hoaread.hh: ... in this
new file, that also handle the --trust-hoa option.
* src/bin/Makefile.am: Add them.
* src/bin/autfilt.cc, src/bin/dstar2tgba.cc, src/bin/ltlcross.cc,
src/bin/ltldo.cc: Use them.
* src/tests/parseaut.test, src/tests/ltldo.test: Adjust, and test
--trust-hoa=no.
* src/tests/complement.test, src/tests/prodor.test,
src/tests/sbacc.test: Adjust.
* wrap/python/spot.py (automata): Add option trust_hoa.
* NEWS: Update.
