For the internal driver we can switch to malloced buffers.  They were
simply not needed with short APDUs.  We may want to keep them in the
ccid_driver_s struct.  We could start with a short buffer and increase
it to ~64k if we get a respective error back from the card.  In general
I would like to limit the allocated memory unless more is needed.  That
driver is quite usable for embedded systems and there RAM is still a
scarce resource.
