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.
