contrib/rbtree license GPL -> LGPL

The latest source of rb.c in the avl-2.0.3 package from GNU/FSF is
now licensed under LGPL, a better license for allowing our partners
to write translators and applications for gluster.

Resubmitting with a BZ. The real question is whether this is okay with
LGPL or whether we should go all the way to a BSD-licensed implementation.
