Changed/renamed utrace probes.

2008-06-06  David Smith  <dsmith@redhat.com>

	* tapsets.cxx (enum utrace_derived_probe_flags): Redefined in
	terms of probe types instead of utrace events.
	(utrace_var_expanding_copy_visitor::visit_target_symbol): Uses new
	utrace_derived_probes_flags values.
	(utrace_builder::build): Handles new probe types and new
	utrace_derived_probes_flags values.
	(utrace_derived_probe_group::emit_probe_decl): Updated to handle
	new utrace_derived_probe_flags values.
	(utrace_derived_probe_group::emit_module_decls): Ditto.  Also
	correctly handles 'begin' events correctly by installing a quiesce
	handler (instead of running the probe directly).
	(register_standard_tapsets): Registers updated utrace probe
	types.

2008-06-06  David Smith  <dsmith@redhat.com>

	* task_finder.c: Added some debug logic.  Use
	'-DDEBUG_TASK_FINDER' to enable.
	(stap_utrace_attach): Renamed from '__stp_utrace_attach'.
	(__stp_utrace_attach_match_filename): Calls callback with
	notification that this is a process or thread event.
	(__stp_utrace_attach_match_tsk): Ditto.
	(__stp_utrace_task_finder_report_clone): Ditto.
	(__stp_utrace_task_finder_report_exec): Ditto.
	(stap_utrace_task_finder_report_death): Ditto.
	(stap_start_task_finder): Ditto.
	(stap_stop_task_finder): Added debug logic.

	* systemtap.base/utrace_p4.exp: Updated for utrace probe changes.
	* systemtap.base/utrace_p5.exp: Ditto.
