2004-10-15  Alexandre Duret-Lutz  <adl@src.lip6.fr>

	Back out all Thomas's changes on emptiness checks since
	2004-08-23.  Some of these will need to be reintegrated more
	slowly and cleanly.

	* src/tgbaalgos/Makefile.am, src/tgbaalgos/gtec/ce.cc,
	src/tgbaalgos/gtec/ce.hh, src/tgbatest/Makefile.am,
	src/tgbatest/emptchk.test, src/tgbatest/ltl2tgba.cc: Revert.
	* src/tgbaalgos/colordfs.cc, src/tgbaalgos/colordfs.hh,

	The computation of the counter example fails the valgrind tests
	and is wrong into two ways: the search stack is generally not a
	path, and does not run until the end of the STL container.
	Remove it.
	* src/tgbaalgos/tarjan_on_fly.cc, src/tgbaalgos/tarjan_on_fly.hh
	(tarjan_on_fly): Do not inherit from the emptiness_search class,
	because the check method will no longer return a counter example.
	(tarjan_on_fly::check): Return only a boolean.
	(tarjan_on_fly::build_counter): Delete.
