Remove global continuations in favour of a per-thread
continuations.

* gdbthread.h (struct thread_info): Add comments around
continuations and intermediate_continuations.
(save_infrun_state, load_infrun_state): Delete continuations and
intermediate_continuations arguments.
* infrun.c (fetch_inferior_event): Only call normal_stop if
stop_soon is NO_STOP_QUIETLY.
(context_switch): Don't context-switch the continuations.
* thread.c (clear_thread_inferior_resources): Discard all
continuations of the thread we're clearing.
(save_infrun_state, load_infrun_state): Delete continuations and
intermediate_continuations arguments, and the code referencing
them.
* utils.c: Include "gdbthread.h".
(cmd_continuation, intermediate_continuation): Delete.
(add_continuation): Add thread_info* argument.  Install the
continuation on it.
(restore_thread_cleanup): New.
(do_all_continuations_ptid, do_all_continuations_thread_callback):
New.
(do_all_continuations): Reimplement.
(discard_all_continuations_thread_callback,
discard_all_continuations_thread): New.
(discard_all_continuations): Reimplement.
(add_intermediate_continuation): Add thread_info* argument.
Install the continuation on it.
(do_all_intermediate_continuations_thread_callback)
(do_all_intermediate_continuations_thread): New.
(do_all_intermediate_continuations): Reimplement.
(discard_all_intermediate_continuations_thread_callback): New.
(discard_all_intermediate_continuations_thread): New.
(discard_all_intermediate_continuations): Reimplement.

* breakpoint.c (until_break_command): Install the continuation on
the current thread.

* defs.h (cmd_continuation, intermediate_continuation): Delete.
(struct thread_info): Forward declare.
(add_continuation, add_intermediate_continuation): Add
thread_info* argument.
(do_all_continuations_thread, discard_all_continuations_thread)
(do_all_intermediate_continuations_thread)
(discard_all_intermediate_continuations_thread): Declare.
* inf-loop.c (inferior_event_handler): In non-stop only run
continuations on the thread that stopped.  In all-stop, run
continuations on all threads.
* infcmd.c (step_once, finish_command): Adjust.
