Fixing this bug alone revealed another bug: parsing never claim or LBTT
automata did not register APs. So this fixes both bugs.
This is the first part of #170.
* spot/twa/twa.hh (register_aps_from_dict): New method.
* spot/parseaut/parseaut.yy: Call it for never claim and LBTT files.
* spot/twaalgos/stats.cc: Simplify using ap_vars().
* tests/core/ltl2tgba.test: Add a test case.
* NEWS: Mention the bugs.
This allows bitvect.hh to compile with icpc 16.0.2, but the whole
project does not yet compile due to a bug in 16.0.2 that prevents
compilation of unordered_map::emplace() from the STL shipped with GCC
5.3.1.
* spot/misc/bitvect.hh: adjust friend declarations.
* bin/common_range.hh: Store the common definition of words.
* bin/autfilt.cc: Use it.
* bin/ltlfilt.cc: Likewise, and implement those two options.
* tests/core/acc_word.test: Test them.
* doc/org/autfilt.org: Augment the last example to point out
that it can now be done with ltlfilt.
* NEWS: Mention the new options.
* spot/twa/twagraph.hh (edges): Do not hide from SWIG.
* spot/graph/graph.hh: Hide stuff that SWIG do not understand.
* python/spot/impl.i: Add some typemaps and fragment to
iterate over the result of twa_graph::edges().
* bin/autfilt.cc: Translate each word as an automaton once,
and do not make a global product of all of them.
* spot/twaalgos/word.cc: Register the atomic propositions used by the
word when converting it into an automaton.
* tests/core/acc_word.test: Add a test case that used to fail, and
another test that make sure some words are not accepted.
* spot/parsetl/fmterror.cc, spot/tl/parse.hh: Add an option to display
shifted diagnostics.
* spot/twaalgos/word.cc: Use the new parser interface and the above
option.
Suggested by Matthias Heizmann. Fixes#109.
* NEWS: notify the new option
* THANKS: add Matthias Heizmann
* bin/autfilt.cc: add new option --accept-word=WORD which filters
automata that accept WORD
* doc/org/autfilt.org: add an example of the new option
* tests/Makefile.am: add core/acc_word.test to the list of test files
* tests/core/acc_word.test: test some uses of the new option
