	Remove the END_SESSION_LAST phase since it was considered to break the
	design. Instead, just use a second step in the END_SESSION phase.

	* gnome-session/gsm-manager.[ch]: (phase_num_to_name): remove
	END_SESSION_LAST phase
	(end_phase): always clean up next_query_clients, and remove
	END_SESSION_LAST phase.
	(on_phase_timeout): remove END_SESSION_LAST phase
	(_client_end_session): change the function signature so that we can
	merge this old function and _client_end_session_last
	(_client_end_session_last): killed
	(_client_end_session_helper): new, helper used for
	do_phase_end_session() since _client_end_session() cannot be directly
	used anymore
	(do_phase_end_session): use _client_end_session_helper(), and save
	session if there's nothing to do
	(do_phase_end_session_last): renamed to...
	(do_phase_end_session_part_2): ... this. Don't reset the phase timeout
	since we're still in the END_SESSION phase. Clean up next_query_clients
	after having used it.
	(start_phase): always clean up next_query_clients, remove
	END_SESSION_LAST phase
	(maybe_save_session): s/END_SESSION_LAST/END_SESSION/
	(on_client_end_session_response): only accept to end a client last if
	we're in END_SESSION. Start the second step of END_SESSION if there's
	no clients that haven't replied, no inhibitor and if there are clients
	to end last. Note that we don't remove the phase timeout here since it
	will either be needed in the second step or will be removed in
	end_phase().
