Log:
IFDHControl(): Add support of dwMaxAPDUDataSize

This property indicates if a reader/driver supports extended APDU or
not.

>From PC/SC v2 part 10 (version 2.02.09 not yet published):
dwMaxAPDUDataSize: Maximal size of data the reader and its driver can support
0: short APDU only.
0<X<=256: forbidden values (RFU)
256 < X <= 0x10000: short and extended APDU of up to X bytes of data
0x10000 < X: invalid values (RFU)
