	Clear stale specific bp_location from former whole breakpoint.
	* breakpoint.c (delete_breakpoint): Move the stale referencing clear
	code ...
	(free_bp_location): ... here.  Rename there the called function to
	bpstat_remove_bp_location_callback.
	(bpstat_remove_breakpoint_callback): Rename to ...
	(bpstat_remove_bp_location_callback): ... here, change DATA resolution
	to struct bp_location.  Change the called function to
	bpstat_remove_bp_location.  Create new declaration for the function.
	(bpstat_remove_breakpoint): Rename to ...
	(bpstat_remove_bp_location): ..., change the parameter to loc, adjust
	code for the new parameter type.
