    Clean up the dissection of ServiceContexts.

    Make the top-level item for a ServiceContext an item for the
    ServiceContext as a while, and put the VSCID under it like other items,
    rather than making the VSCID the top-level item.

    Don't dissect the VSCID using the value_string field for the Object
    Management Group's SCIDs; use that value_string field for the SCID if
    the VSCID is 0 (meaning "Object Management Group"), and have no
    value_string field for the VSCID otherwise (the interpretation of the
    SCID depends on the value of the VSCID).

    Dissect the encapsulation information even for unknown ServiceContexts.

    If the ServiceContext's length is bigger than what it's supposed to be,
    throw an exception if it's also bigger than the data available in the
    packet; this squelches a run-time warning in that case.
