    packet-ehdlc: Update with results from better understanding the protocol

    The Ericsson HDLC format inside L2TP is not publicly documented, so when
    I originally wrote the code, I was basically just looking at hex-dumps
    of protocol traces and trying to ge an initial understanding. By now,
    that understanding has significantly matured, so let's update the
    dissector accordingly.

    The major changes are regarding the understanding that there is not a
    message type, but in fact a compressed SAPI and compressed TEI field.

    Based on this, we can discriminate on whether there will be a HDLC/LAPD
    header to follow, or whether there's actual user data (TRAU frame
    replacement) following.
