Since RTMPT is a TCP protocol, does it make sense to have it use
tcp_dissect_pdus() rather than have its own packet reassembly (where presumably
the large memory allocation happens)?  I think tcp_dissect_pdus may be smarter
with the memory usage, although I don't know RTMPT, so I'm not sure if it makes
sense for the protocol.
