ui: mix misleading comments & return types of VNC I/O helper methods
While the QIOChannel APIs for reading/writing data return ssize_t, with negative value indicating an error, the VNC code passes this return value through the vnc_client_io_error() method. This detects the error condition, disconnects the client and returns 0 to indicate error. Thus all the VNC helper methods should return size_t (unsigned), and misleading comments which refer to the possibility of negative return values need fixing. Signed-off-by: Daniel P.
