There has been long time confusion in the windows cache manager because
there are cm_conn object ptrs call connp and rx_connection object ptrs
call connp and rx_call object ptrs called callp and rx_connection object
ptrs called callp.

From now on, rxconnp is a ptr to an rx_connection object;
rxcallp is a ptr to an rx_call object; and connp is a ptr to an
cm_conn object.
