commit 4398554be49b5ed1d55f6e371426774fecfa4235
Author: Frediano Ziglio <fziglio at redhat.com>
Date: Fri Sep 7 11:31:46 2018 +0100
spice-session: Remove last usage of ring_ functions
Not much sense to reimplement a list using Ring type.
This patch maintains the stability of the iterators and
the order of the items in the container.
