Changes to OCD support to support wiggler box as well as
        target boxes:
        * ocd.c: change speed in init command to 0 from 80,
        add (temporary) logging commands to help debugging,
        (ocd_open): if "target ocd wiggler lpt" then use special
        ser-ocd.c serial interface which communicates with Wigglers.dll,
        otherwise do as we did before
        (ocd_get_packet): add OCD_LOG_FILE and OCD_SET_CONNECTION to
        switch of known commands of len 0
        * ocd.h: add OCD_LOG_FILE
        * serial.c (serial_open): do serial_interface_lookup on ocd
        in the case of ocd
        * ser-ocd.c: add buffer to contain responses from sending a
        command to the Wigglers.dll.
        (ocd_readchar): return curr char from buffer and increment ptr
        (ocd_write): send buffer to Wigglers.dll, storing response in
        return buffer and initializing curr location ptr to start of
        buffer.
