	* breakpoint.c (user_settable_breakpoint): Delete.
	(user_breakpoint_p): Remove check on user_settable_breakpoint.
	(delete_command): Check user_breakpoint_p instead of looking at
	the breakpoint's type.
	(disable_command): Ditto.
	(enable_command): Ditto.
	(delete_trace_command): Use user_breakpoint_p instead of looking
	at the breakpoint number directly.  When checking if there are
	user visible tracepoints, in order to know whether to ask the user
	for confirmation, check whether the breakpoint is actually a
	tracepoint.
