	* continuations.h (continuation_ftype): Add `err' parameter.
	Document parameters.
	(do_all_continuations, do_all_continuations_thread)
	(do_all_intermediate_continuations)
	(do_all_intermediate_continuations_thread)
	(do_all_inferior_continuations): Add `err' parameter.
	* continuations.c (do_my_continuations_1, do_my_continuations)
	(do_all_inferior_continuations, do_all_continuations_ptid)
	(do_all_continuations_thread_callback)
	(do_all_continuations_thread, do_all_continuations)
	(do_all_intermediate_continuations_thread_callback)
	(do_all_intermediate_continuations_thread)
	(do_all_intermediate_continuations): Add `err' parameter, and pass
	it down all the way to the continuations proper.
	* inf-loop.c (inferior_event_handler): If fetching an inferior
	event throws an error, don't pop the target, and still call the
	continuations, but with `err' set.  Adjust all other continuation
	calls.
	* breakpoint.c (until_break_command_continuation): Add `err'
	parameter.
	* infcmd.c (step_1_continuation): Add `err' parameter.  Don't
	issue another step if `err' is set.
	(struct until_next_continuation_args): New.
	(until_next_continuation): Add `err' parameter.  Adjust.
	(until_next_command): Adjust.
	(struct finish_command_continuation_args): Add `thread' field.
	(finish_command_continuation): Add `err' parameter.  Handle it.
	(finish_forward): Adjust.
	(attach_command_continuation): Add `err' parameter.  Handle it.
	* infrun.c (infrun_thread_stop_requested_callback): Adjust to
	cancel the continuations.
	* interps.c (interp_set): Adjust to cancel the continuations.
	* thread.c (clear_thread_inferior_resources): Adjust to cancel the
	continuations rather than discarding.
	(free_thread): Don't clear thread inferior resources here.
	(delete_thread_1): Do it here instead.  And do it before removing
	the thread from the threads list.  Tag the thread as exited before
	clearing thread inferior resources.
