acceptance conditions, calling remove_fin() is not necessary anymore.

On some architectures (e.g., ARM, or even some -flto setups on Intel)
C++ exceptions to not traverse the C functions. So even if the C++
main() has a try/catch, it will not catch the exception thrown by C++
code called from the argp module (which is compiled in C).
* bin/common_setup.cc, bin/common_setup.hh: Define some macros
and function to factorize exception handling.

Protect all parse_opt() functions, even those where there is currently
no exception risk.
Suggested by Victor Khomenko.

* doc/org/hierarchy.org: Use it.

* bin/common_output.cc: Typo.
* NEWS: Mention the new option.
This was prompted by reports by Andrew Wells and Yong Li.
* NEWS, doc/tl/tl.tex: Document the changes.
* THANKS: Add Andrew.
* bin/ltlfilt.cc: Match --ltl before --from-ltlf if needed.
* spot/parsetl/parsedecl.hh, spot/parsetl/parsetl.yy,

* tests/core/ltlfilt.test, tests/core/sugar.test,
tests/core/utf8.test: More tests.
std::cerr will flush after each operator<< by default, so it's simpler
to use \n instead of std::endl, especially if we can merge \n into the
previous string. Ideally we should prefer \n for std::cout as well,
but there are reasonable cases where we want to call std::endl there,
so it's hard to enforce.
* tests/sanity/style.test: Diagnose occurrences of cerr.*<<.*endl.

* bin/autcross.cc: Let complement() decide how to complement automata.
Do not apply remove_fin(), because we have a generic emptiness check
now. Use intersecting_word() instead of product()+accepting_word() so
that the former can maybe be optimized in the future.
* tests/core/autcross2.test: Adjust test case to use TGBA instead
of monitors, as calling complement() had a side-effect of setting
the "weak" property on the input.

output_aborter argument to abort if the output is too large.
* bin/ltlcross.cc: Use complement() with an output_aborter
so that ltlcross will not attempt to build complement larger
than 500 states or 5000 edges. Add --determinize-max-states
and --determinize-max-edges options.

code and documentation.

results.

language_containment_checker.contains()
* bin/autfilt.cc: Adjust usage.
ltlsynt now offers two algorithms: one where splitting occurs before
determinization (the historical one) and one where determinization
occurs before splitting.
* bin/ltlsynt.cc: here
* tests/core/ltlsynt.test: test it and refactor test file

ltl-split even for BA/TGBA, but only of conjunctions with GF(..)
in those cases.

Implementing this required to extend our interface two support
two-parameter patterns.

* bin/genltl.cc: Add --sejk-f.
* bin/common_output.cc, bin/common_output.hh: Adjust to handle
