Per-thread commands.

	* gdbthread.h: Remove unneeded forward declarations.
	Include "inferior.h".
	(struct thread_info): Add continuations,
	intermediate_continuations, proceed_to_finish, step_over_calls,
	stop_step, step_multi and stop_signal members.
	(save_infrun_state): Add continuations,
	intermediate_continuations, proceed_to_finish, step_over_calls,
	stop_step, step_multi, stop_signal and stop_bpstat parameters.
	(load_infrun_state): Add continuations,
	intermediate_continuations, proceed_to_finish, step_over_calls,
	stop_step, step_multi, stop_signal and stop_bpstat parameters.

	* thread.c (load_infrun_state): In non-stop mode, load
	continuations, intermediate_continuations, proceed_to_finish,
	step_over_calls, stop_step, step_multi and stop_signal.
	(save_infrun_state): Store continuations,
	intermediate_continuations, proceed_to_finish, step_over_calls,
	stop_step, step_multi, stop_signal and stop_bpstat.
	(save_infrun_state): Store continuations,
	intermediate_continuations, proceed_to_finish, step_over_calls,
	stop_step, step_multi, stop_signal and stop_bpstat.
	(free_thread): Clear The thread's stop_bpstat.

	* inferior.h (context_switch_to): Declare.

	* infrun.c (ecss): New global.
	(context_switch): Context switch continuations,
	intermediate_continuations, proceed_to_finish, step_over_calls,
	stop_step, step_multi, stop_signal and stop_bpstat.
	(wait_for_inferior): Use global ecss.
	(async_ecss, async_ecs): Delete.
	(fetch_inferior_event): Use global ecss.
	(context_switch_to): New.

	* top.c (execute_command): In non-stop, only check if the current
	thread is running, in all-stop, check if there's any thread
	running.

	* breakpoint.c (bpstat_remove_breakpoint): New.
	(bpstat_remove_breakpoint_callback): New.
	(delete_breakpoint): Clear the stop_bpstats of all threads.

	* mi/mi-main.c (mi_cmd_execute): In non-stop, only check if the
	current thread is running, in all-stop, check if there's any
	thread running.

	* Makefile.in (gdbthread_h): Depend on $(inferior_h).
