	PR breakpoints/13776:
	* breakpoint.c (breakpoint_init_inferior): Delete step-resume
	breakpoints.
	(delete_longjmp_breakpoint_at_next_stop): New.
	* breakpoint.h (delete_longjmp_breakpoint_at_next_stop): Declare.
	* target.c (generic_mourn_inferior): Call mark_breakpoints_out
	before deleting the inferior.  Add comments.
	* thread.c (clear_thread_inferior_resources): Don't delete lonjmp
	breakpoints immediately, but only on next stop.  Move that code
	next to where we mark other breakpoints for deletion.
