[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.
