    Rename IPPROTO 33 from SEP to DCCP
    
    IPPROTO 33 is DCCP in the IANA Registry:
    https://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml
    
    IPPROTO_SEP was added about 20 years ago in r33804. The entries were added
    straight from RFC1700, without regard to whether they were used.
    
    The reference in RFC1700 for SEP is '[JC120] <mystery contact>', this is an
    indication that the protocol number was probably in use in a private network.
    
    As RFC1700 is no longer the authoritative list of internet numbers and that
    IANA assinged 33 to DCCP in RFC4340, change the header to the actual
    authoritative source.
