	* tapsets.cxx (utrace_derived_probe_group::emit_probe_decl):
	Pushed quiesce logic down into the task_finder layer.
	(utrace_derived_probe_group::emit_module_decls): Removed quiesce
	handler routines.  Syscall probe handler detaches if systemtap
	state isn't correct.

	* task_finder.c (__stp_utrace_attach_match_filename): Don't call
	the callback when the interesting thread is found, call it when
	the tread is quiesced.
	(stap_start_task_finder): Ditto.
	(__stp_utrace_task_finder_target_quiesce): Call the callback.
