Add backlink from lwp_info to thread_info.
* gdbthread.h (add_thread): Change result type to struct thread_info *.
* inferiors.c (add_thread): Change result type to struct thread_info *.
All callers updated.
(add_lwp): Call add_thread here instead of in callers.
All callers updated.
* linux-low.h (get_lwp_thread): Rewrite.
(struct lwp_info): New member "thread".
This speeds up gdbserver attach in non-stop mode because now get_lwp_thread
doesn't do a linear search for the corresponding thread_info object.
