* server.c (process_serial_event): Re-return unsupported, not

error, if the type isn't recognized.  Re-allow supporting only
	insert or remove packets.  Also call require_running for
	breakpoints.  Add missing break statement to default case.  Tidy.
	* target.h (struct target_ops): Rename insert_watchpoint to
	insert_point, and remove_watchpoint to remove_point.

	* linux-low.h (struct linux_target_ops): Likewise.
