    Clean up handling of counted blobs of bytes.
    
    Don't treat the count+blob as itself a blob of bytes; use FT_NONE.
    Create it with an unknown length (-1, meaning "to end of packet, for
    now"), and set its length once we've finished dissecting it.  Dissect
    the raw bytes of a prefixed-bytes item regardless of whether we're
    building a protocol tree or not.
    
    This means we do a better job of handling a too-large length; instead of
    overflowing the offset, we throw an exception and stop dissecting, so we
    don't run the risk of looping infinitely.
