// CSecurity - class on the client side for handling security handshaking. A
// derived class for a particular security type overrides the processMsg()
// method. processMsg() is called first when the security type has been
// decided on, and will keep being called whenever there is data to read from
// the server until either it returns 0, indicating authentication/security
// failure, or it returns 1, to indicate success. A return value of 2
// (actually anything other than 0 or 1) indicates that it should be called
// back when there is more data to read.
//
// Note that the first time processMsg() is called, there is no guarantee that
// there is any data to read from the CConnection's InStream, but subsequent
// calls guarantee there is at least one byte which can be read without
// blocking.
