	Merge from setuid-branch.  Changes also by Martin Hunt
	<hunt@redhat.com>.
	
	* staprun.c (init_staprun): Drop CAP_SYS_ADMIN when we're done
	with it.
	(main): Calls parse_modpath instead of path_parse_modname.  Just
	call parse_modpath with argv[optind]. Let it allocate and set
	modpath and modname.  If no modulename was given, display usage
	and exit.  Drop CAP_SYS_NICE when we're done with it.  Set
	atexit(exit_cleanup) so cleanup always gets called and modules get
	removed.  Call handle_symbols.
	(run_stapio): Set argv[0] to stapio so that it executes as itself
	instead of staprun.
	(cleanup): Only do cleanups once and only try to remove module
	when appropriate.
	(exit_cleanup): New. Calls cleanup().
	(mountfs): Sets uid to root before making directory and then
	restores uid.
	(setup_ctl_channel): Uses DEBUGFS define and improved
	error message.
	(setup_relayfs): Ditto.
	(setup_oldrelayfs): Uses DEBUGFS and RELAYFS defines.
	(run_stp_check): Replaced by mountfs().
	(mountfs): New function.  Replaces an external script with C code.
	(init_staprun): Calls mountfs() instead of run_stp_check().
	
	* staprun.h: Renamed path_parse_modname to parse_modpath.  Added
	MODULE_NAME_LEN define.  Added [_][p]err macros.  Removed
	VERSION_CMD.
	
	* mainloop.c (cleanup_and_exit): Make sure initialized is 2
	before exiting with code 2.
	(stp_main_loop): Set initialized to 2 when STP_TRANSPORT
	is received. Call cleanup_and_exit() with proper status.
	(start_cmd): exit 1 instead of -1.
	(system_cmd): Ditto.
	(init_staprun): Renamed init_stapio.
	(cleanup_and_exit): Set exit status.
	
	* cap.c: New file.
	* common.c: New file.
	* stapio.c: New file.
	* staprun_funcs.c: New file.
	* Makefile: Removed.
	
	* symbols.c (get_sections): Move the filter code up so that
	uninteresting section names are filtered out before
	attempting to open them.
	(do_kernel_symbols): Better detect overfow conditions and realloc
	new space.
	(do_module): After sending all modules, send a null message to
	indicate we are finished.
	
	* ctl.c (init_ctl_channel): When attempting to attach, if the
	control channel doesn't exist, print a better error message.
	
	* relay_old.c (init_oldrelayfs): Errors out if
	open_relayfs_files() couldn't open any files.
	
	PR 4795
	* mainloop.c (send_request): Fixed buffer overflow check.
	* staprun.h: Added buffer overflow checking versions of
	strcpy/sprintf/snprintf.
	* common.c (path_parse_modname): Checks for overflows on
	strcpy/sprintf/snprintf.
	(read_buffer_info): Ditto.
	* ctl.c (init_ctl_channel): Ditto.
	* relay.c (init_relayfs): Ditto.
	* relay_old.c (open_relayfs_files): Ditto.
	(init_oldrelayfs): Ditto.
	* staprun_funcs.c (insert_module): Ditto.
	(check_path): Ditto.
	* symbols.c (get_sections): Ditto.
