	Changes to separate the symbols from the command channel.

	* cap.c (init_cap): Add CAP_DAC_OVERRIDE.
	* staprun.h: Change init_ctl_channel prototype.
	* ctl.c (init_ctl_channel): Modify to open either
	a command or symbol channel. Use ".cmd" and ".symbols"
	as the new names.
	* mainloop.c (init_stapio): Call init_ctl_channel(0);
	* staprun.c (cleanup): Call stop_symbol_thread().
	(main): Call start_symbol_thread().
	* staprun_funcs.c (handle_symbols): Make a thread.
	(start_symbol_thread): New.
	(stop_symbol_thread): New.
