	* include/vaucanson/algorithms/is_ambiguous.hxx:
	  We need to create a map of correspondance to work with the set
	  filled by product. This is related to the copy of the automaton

	* internal/evaluation.hxx,
	* rw_composition.hxx:
	  Correct errors related to state renumbering and automata copy.
	  hstates_t are linked to an automaton and should not be used on
	  an other one. To do this, we must either convert them back to
	  integer when possible and ask for the corresponding state, or
	  use a map to link states from one automaton to the other.

	* bmig/bmig_handlers_op.hxx:
	  Fix hstate_t operators: we now compare the address of the int
	  instead of its value. It allows correct use of sets or maps
	  in combination with state renumbering.

	* bmig_graph_impl.hxx:
	  Correction of the has_state method.

	* include/vaucanson/standard_algorithms.hh:
	Add #include for the new algorithms
	* taf-kit/src/b_commands.cc,
	* taf-kit/src/z_commands.cc:
	Remove previous is_empty, add is_empty and has_succ_comp
	to the list displayed with -l.
	* taf-kit/src/common_commands.hh:
	Add #include for the new algorithms.  This may be
	unnecessary.

	This fixes tickets #37 and #119.
	is_empty <aut> returns true if aut has no state,
	false otherwise.
	has_succ_comp <aut> returns true if aut has at least one
	state that is both accessible and co-accessible.

	Note that is_empty behaves differently from the version
	that was previously available in taf-kit.
