Instead of using a Ring (and having a ring item link in every pipe item), store them in a GQueue. This also necesitated changing RedCharDeviceVDIPort->priv->read_bufs to a GList as well. Also Optimise client pipe by passing pipe position instead of data. This avoids having the search the data scanning all the queue changing the order of these operations from O(n) to O(1).
