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.

It currently works only for deterministic automata.
* By default, autfilt does not simplify automata (this has not
changed), as if the --low --any options where used. But now, if
changed), as if the --low --any options were used. But now, if
one of --small, --deterministic, or --any is given, the
optimization level automatically defaults to --high (unless
specified otherwise). For symmetry, if one of --low, --medium, or
--high is given, thn the translation intent defaults to --small
--high is given, then the translation intent defaults to --small
(unless specified otherwise).
* autfilt, dstar2tgba, ltlcross, and ltldo now trust the (supported)
automaton properties declared in any HOA file they read. This can
be disabled with option --trust-hoa=no.
* ltlgrind FILENAME[/COL] is now the same as
ltlgrind -F FILENAME[/COL] for consistency with ltlfilt.

* The HOA parser will diagnose any version that is not v1, unless it
looks like a subversion of v1 and no parse error was detected.
* The way to pass option to the automaton parser has been changed to
make it easier to introduct new options. One such new option is
"trust_hoa": when true (the default) supported properties declared
in HOA files are trusted even if they cannot be easily be verified.
* ltl_simplifier renamed to tl_simplifier.

skip automata ended with --ABORT--.
