* src/tgbaalgos/hoaf.cc, src/tgbaalgos/hoaf.hh: Rename to...
* src/tgbaalgos/hoa.cc, src/tgbaalgos/hoa.hh: ... these, and
fix the function names.
* src/tgbaalgos/Makefile.am, src/bin/autfilt.cc,
src/bin/dstar2tgba.cc, src/bin/ltl2tgba.cc, src/tgbatest/ltl2tgba.cc:
Adjust all calls.

* src/misc/timer.hh (stopwatch): New class, implemented on top
of C++11's std::chrono::high_resolution_clock.
* src/bin/dstar2tgba.cc, src/bin/ltl2tgba.cc, src/bin/ltlcross.cc:
Use it in lieu of gethrxtime(), so we do not need to distribute
gethrxtime anymore.

The specifications are at http://adl.github.io/hoaf/

* src/tgbaalgos/hoaf.cc, src/tgbaalgos/hoaf.hh: New files.
* src/tgbaalgos/Makefile.am: Add them.
* src/bin/dstar2tgba.cc, src/bin/ltl2tgba.cc,
src/tgbatest/ltl2tgba.cc: Add option to output HOA.
* NEWS: Mention it.

A type such as 'const tgba_digraph*' and 'tgba_digraph*' are replaced
by 'const_tgba_digraph_ptr' and 'tgba_digraph_ptr'.  Additionally 'new
tgba_digraph(...)' is replaced by 'make_tgba_digraph(...)'.

This convention is followed by all automata types. Those smart
pointers should normally be passed by const reference as input of
function to avoid the atomic increments/decrements, but I probably
missed a few, as this huge patch took me nearly 12h.

(setup): Hook the display_version function.
(argp_program_bug_address): Define this common variable here.
* src/bin/genltl.cc, src/bin/ltl2tgba.cc, src/bin/ltl2tgta.cc,
src/bin/ltlfilt.cc, src/bin/randltl.cc (argp_program_bug_address,

* src/bin/genltl.cc, src/bin/ltl2tgba.cc, src/bin/ltl2tgta.cc,
src/bin/ltlfilt.cc, src/bin/randltl.cc: Adjust.

* src/bin/common_finput.cc, src/bin/common_finput.hh: Define the
processor class.
* src/bin/ltl2tgba.cc, src/bin/ltl2tgta.cc, src/bin/ltlfilt.cc:
Simplify accordingly.

files...
* src/bin/ltl2tgba.cc: ... and use them here.

Report error when writing to std::cout failed.  This is mainly
motivated by ltlfilt not being killed by SIGPIPE on lip6's OSX
buildfarm (SIGPIPE is probably ignored when the build is started), but
it could detect other errors such as a disk full.
