gdb:

	* breakpoint.c: Removed always_inserted_auto, always_inserted_on,
	always_inserted_off, and always_inserted_enums.
	Change always_inserted_mode's type to 'enum auto_boolean'.
	(show_always_inserted_mode, breakpoint_always_inserted_mode): Update
	callers.
	(_initialize_breakpoint): Call add_setshow_auto_boolean_cmd instead
	of add_setshow_enum_cmd.
	* infrun.c: Remove can_use_displaced_stepping_auto,
	can_use_displaced_stepping_on, can_use_displaced_stepping_off, and
	can_use_displaced_stepping_enum.
	Change can_use_displaced_stepping's type to 'enum auto_boolean'.
	(show_can_use_displaced_stepping, use_displaced_stepping): Update callers.
	(_initialize_infrun): Call add_setshow_auto_boolean_cmd instead of
	add_setshow_enum_cmd.
