From Ricardo Barroetave�a: support dissectors that are handed

reassembled TCP data being able to indicate that they need still more
reassembly, so that, for example, a dissector can indicate that it needs
reassembly in order to dissect a header that says how long the PDU is
and, when that reassembly is done and it dissects the header, it can
then indicate that it needs more reassembly to get the entire PDU.
