This patch adds to the CVF depayloader the capability to regroup H.264 fragmented FU-A packets. After all packets are regrouped, they are added to the "stash" of H.264 NAL units that will be sent as soon as an AVTP packet with M bit set is found (usually, the last fragment). Unrecognized fragments (such as first fragment seen, but with no Start bit set) are discarded - and any NAL units on the "stash" are sent downstream, as if a SEQNUM discontinuty happened.
