Register RPC as dissector for both TCP and UDP port 111 which is used by ONC-RPC/PORTMAPPER 

The reason for doing this is to allow a user to pick RPC as a protocol offered
by DecodeAs...

Why:
If ethereal has tcp-reseembly enabled, the heuristic dissector for rpc will not even attempt to find RPC packets.
If no PORTMAPPER/GETPORT are available either in the capture there is
currently no way for ethereal to know/learn that the conversation is ONC-RPC.
This at least will allow users to manually tell ethereal that such a conversation is ONC-RPC.
