ZOOM: special options to control APDU logging

Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
logging of APDUs until "saveAPDU" option is set again. If logging is
already enabled the effect is that current APDU buffer is cleared.
Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
logging (default behavior on new connection).
The APDUs sent/received can be obtained by using
Using ZOOM_connection_option_get(c, "APDU") or
ZOOM_connection_option_getl(c, "APDU", &l).
