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. * bin/autcross.cc, bin/autfilt.cc, bin/common_aoutput.cc, bin/common_color.cc, bin/common_finput.cc, bin/common_hoaread.cc, bin/common_output.cc, bin/common_post.cc, bin/common_trans.cc, bin/dstar2tgba.cc, bin/genaut.cc, bin/genltl.cc, bin/ltl2tgba.cc, bin/ltl2tgta.cc, bin/ltlcross.cc, bin/ltldo.cc, bin/ltlfilt.cc, bin/ltlgrind.cc, bin/ltlsynt.cc, bin/randaut.cc, bin/randltl.cc: Protect all parse_opt() functions, even those where there is currently no exception risk.
