Split the GDBRemoteCommunication class into three classes:

GDBRemoteCommunication - The base GDB remote communication class
GDBRemoteCommunicationClient - designed to be used for clients the connect to
                               a remote GDB server
GDBRemoteCommunicationServer - designed to be used on the server side of a
                               GDB server implementation.
