* linux-nat.c (lin_lwp_attach_lwp): Return a status. Do not
add the LWP to our list until we are attached. Warn instead
of erroring if the attach fails.
* linux-nat.h (lin_lwp_attach_lwp): New prototype.
* linux-thread-db.c (attach_thread): Call lin_lwp_attach_lwp
directly. Do not add the thread to our list until we are
successfully attached.
* config/nm-linux.h (lin_lwp_attach_lwp, ATTACH_LWP): Delete.
