Rename Distributed Checksum Clearinghouse protocol from "DCCP" to just

"DCC".  Googling for

	DCCP "Distributed Checksum Clearinghouse Protocol"

finds only hits related to Ethereal/Wireshark, either on the Ethereal or
Wireshark Web site, or on discussions where Datagram Congestion Control
Protocol developers were griping that Ethereal/Wireshark already used
DCCP for the Distributed Checksum Clearinghouse protocol.

Next step: fix the Datagram Congestion Control Protocol dissector.
