[DCCP]: Update documentation references.

Updates the references to spec documents throughout the code, taking into
account that

* the DCCP, CCID 2, and CCID 3 drafts all became RFCs in March this year

* RFC 1063 was obsoleted by RFC 1191

* draft-ietf-tcpimpl-pmtud-0x.txt was published as an Informational
  RFC, RFC 2923 on 2000-09-22.

All references verified.

           The Datagram Congestion Control Protocol (DCCP) is a transport
           protocol that implements bidirectional, unicast connections of
           congestion-controlled, unreliable datagrams. It should be suitable
           for use by applications such as streaming media, Internet telephony,
-          and on-line games
+          and on-line games.
 
           To compile this protocol support as a module, choose M here: the
           module will be called dccp.
