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.
The previous code was sometime doing the work of remove_fin() in
addition to complementing the acceptance conditions. This separate
the two operations clearly. Also the specialized code for
complementing weak automata is now a specialized code for remove_fin()
on weak automata.
* src/twaalgos/dtgbacomp.hh, src/twaalgos/dtgbacomp.cc: Rename as ...
* src/twaalgos/complement.hh, src/twaalgos/complement.cc: ... these.
* src/twaalgos/Makefile.am: Adjust.
* src/twaalgos/complement.hh (dtgba_complement): Rename as ...
(dtwa_complement): ... this, and restrict the purpose to completion
and accetance complementation. Further acceptance simplification
can be done with remove_fin() and to_generalized_buchi().
* src/twaalgos/remfin.cc (remove_fin): Specialize handling of weak
automata using the code that was originally in dtgba_complement().
Also mark the output as state-based when the input has to Inf.
* src/twaalgos/postproc.cc, src/twaalgos/postproc.hh: Make sure
scc_filter is always called after to_generalized_buchi().
* bench/stutter/stutter_invariance_randomgraph.cc,
src/bin/ltlcross.cc, src/tests/ikwiad.cc, src/twaalgos/minimize.cc,
src/twaalgos/powerset.cc, src/twaalgos/stutter.cc: Adjust usage.
* src/tests/dstar.test, src/tests/ltl2dstar4.test,
src/tests/remfin.test: Adjust expected outputs.
* wrap/python/spot_impl.i: Export dtwa_complement().
Flatten the formula ltl::formula hiearchy into a single ltl::vnode that
has an enumerator to distinguish the types of node, and a common
interface to access children, update reference counts, etc. The
ltl::formula class is now a thin wrapper around an ltl::vnode pointer to
keep track of reference counts automatically. Visitor are not used
anymore; we now have map() and traversor() methods that are more
concise.
This basically fixes#43, but should be followed by some fine tuning
that should now be localized to the formula.hh and formula.cc files.
Some statistics about this patch. I started working on it on Sep 9, had
a first compiling version two weeks later on Sep 22, and it then took 5
days to fixes the ~70 distincts bugs that were introduced during the
conversion. About 13200 lines were modified, and one third of those
were removed.

including what was in separate nearby files.

This actually performs three related changes, but separating them
would be quite inconvenient.
1) rename tostring.hh to print.hh a welcome side-effect is that
I could fix several files that included this file for not reason.
2) de-overload some of the to_string functions, and rename them
as follow:
to_string -> print_psl, print_sere, str_psl, str_sere
to_utf8_string -> print_utf8_psl, print_utf8_sere,
str_utf8_psl, str_utf8_sere
to_spin_string -> print_spin_ltl, str_spin_ltl
to_wring_string -> print_wring_ltl, str_wing_ltl
to_lbt_string -> print_lbt_ltl, str_lbt_ltl
to_latex_string -> print_latex_psl, str_latex_psl
to_sclatex_string -> print_sclatex_psl, str_sclatex_psl
Now it is clearer what these functions do, and their restrictions.
3) all those print_* functions now take the stream to write onto
as their first argument. This fixes#88.
* src/ltlvisit/tostring.cc, src/ltlvisit/tostring.hh: Rename into...
* src/ltlvisit/print.cc, src/ltlvisit/print.hh: ... those, and make

Because scc_info does not perform a full emptiness check, it is not
always able to tell whether an SCC is accepting if the acceptance
condition use Fin primitives. This introduce is_rejecting_scc() in
addition to to is_accepting_scc(). Only one of them may be true, but
they can both be false if scc_info has no idea whether the SCC is
accepting.

Suggested by Joachim Klein.
When a bogus formula is found by ltlcross, the --grind=FILENAME option
tries to find a smaller formula for which the bug is still present, and
outputs it in FILENAME.
* src/bin/ltlcross.cc: Add the --grind option.
* doc/org/ltlcross.org: Document the --grind option.
* src/ltltest/ltlcrossgrind.test: Test it.
* src/ltltest/Makefile.am: Add test.
This is a huge patch, that took over a month to complete. The bit sets
are currently restricted to what 'unsigned can store', but it should be
easy to extend it to 'uint64_t' should we need it.
* NEWS: Update.
* src/tgba/acc.hh: New file.
* src/tgbatest/acc.cc, src/tgbatest/acc.test: Test it.
* src/tgba/tgbakvcomplement.cc, src/tgba/tgbakvcomplement.hh,
src/tgba/tgbasgba.cc, src/tgba/tgbasgba.hh: Delete. The KV
complementation is too slow to be used in practice, and I somehow broke
it during the conversion to bitsets. The tgba->sgba conversion was only
used for the KV complementation, and should be better redone on
tgba_digraph_ptr should it be needed again.
