Introduce an emptiness-check interface, and modify the existing

Browse source 
algorithms to conform to it, uniformly.  This will unfortunately
break third-party code that were using these algorithms.
* src/tgbaalgos/emptiness.cc, src/tgbaalgos/emptiness.hh: New files.
* src/tgbaalgos/Makefile.am: New files.
* src/tgbaalgos/magic.cc, src/tgbaalgos/magic.hh: Adjust to
conform to the new emptiness-check interface.
* src/tgbaalgos/gtec/ce.cc, src/tgbaalgos/gtec/ce.hh,
src/tgbaalgos/gtec/gtec.cc, src/tgbaalgos/gtec/gtec.hh,
src/tgbaalgos/gtec/status.cc, src/tgbaalgos/gtec/status.hh:
Likewise.  The classes have been renamed are as following
  emptiness_check -> couvreur99_check
  emptiness_check_shy -> couvreur99_check_shy
  counter_example -> couvreur99_check_result
* src/tgbatest/ltl2tgba.cc, iface/gspn/ltlgspn.cc, iface/gspn/ssp.hh,
iface/gspn/ssp.cc: Adjust to renaming and new interface.
