	* target.h (struct target_ops): Add insert_watchpoint,
	remove_watchpoint, stopped_by_watchpoint, stopped_data_address function
	pointers for hardware watchpoint support.
	* linux-low.h (struct linux_target_ops): Ditto.
	* linux-low.c (linux_insert_watchpoint, linux_remove_watchpoint)
	(linux_stopped_by_watchpoint, linux_stopped_data_address): New.  Add
	to linux_target_ops.
	* remote-utils.c (prepare_resume_reply): Add watchpoint information to
	reply packet.
	* server.c (main): Recognize 'Z' and 'z' packets.
