	not cache th or ti.
	(thread_db_map_id2thr, lwp_from_thread): Delete functions.
	(thread_from_lwp): Assert that the LWP is set.  Do not add TID to the
	new PTID.
	(attach_thread): Handle an already-existing thread.  Use
	add_thread_with_info.  Cache the th and tid.
	(detach_thread): Verify that private was set.  Remove verbose
	argument and printing.  Update caller.

	* thread.c (add_thread_with_info): New.
	(add_thread): Use it.
	* linux-nat.c (find_thread_from_lwp): Delete.
