13eefba by Guy Harris (guy@xxxxxxxxxxxx):

    Fail more cleanly if the file has no records.
    
    If we have no records, we can't determine the link-layer type.
    
    Also:
    
    Use more signed values, and do more sanity checks on the file header and
    TLVs to make sure we don't run into the first packet.
    
    When writing the file header, accumulate the header length/first packet
    offset in a 32-bit variable, and stuff it into the
    offset-to-first-packet fields (plural) once we're done.
