	* breakpoint.h (print_recreate_thread): Declare.
	(struct breakpoint): Move step_count, pass_count,
	number_on_target, static_trace_marker_id,
	static_trace_marker_id_idx ...
	(struct tracepoint): ... to this new struct.
	(get_tracepoint, get_tracepoint_by_number_on_target)
	(get_tracepoint_by_number): Change return type to struct
	tracepoint pointer.
	* breakpoint.c (is_tracepoint_type): New, factored out from
	is_tracepoint.
	(is_tracepoint): Adjust.
	(print_one_breakpoint_location): Cast to struct tracepoint as
	necessary, and adjust.
	(print_recreate_catch_fork, print_recreate_catch_vfork)
	(print_recreate_catch_syscall, print_recreate_catch_exec): Call
	print_recreate_thread.
	(init_breakpoint_sal): New, factored out from
	create_breakpoint_sal.
	(create_breakpoint_sal): Reimplement.
	(create_breakpoint): Allocate a struct tracecepoint if the caller
	wanted a tracepoint.  Use init_breakpoint_sal and
	install_breakpoint.
	(print_recreate_ranged_breakpoint, print_recreate_watchpoint)
	(print_recreate_masked_watchpoint)
	(print_recreate_exception_catchpoint): Call print_recreate_thread.
	(tracepoint_print_one_detail): Adjust.
	(tracepoint_print_recreate): Adjust.  Call print_recreate_thread.
	Dump the pass count here.
	(update_static_tracepoint): Adjust.
	(addr_string_to_sals): Adjust.
	(create_tracepoint_from_upload): Adjust.  Change return type to
	struct tracepoint pointer.

	pointer, and adjust.
	(trace_pass_command): Adjust.
	(get_tracepoint, get_tracepoint_by_number_on_target)
	(get_tracepoint_by_number): Change return type to struct
	tracepoint pointer, and adjust.
	(print_recreate_thread): New, factored out from save_breakpoints.
	(save_breakpoints): Don't print thread and task and passcount
	recreation here.
	* remote.c (remote_download_tracepoint): Adjust.
	* tracepoint.c (trace_actions_command, validate_actionline)
	(start_tracing, tfind_1, trace_find_tracepoint_command)
	(trace_dump_command): Adjust.
