Maybe better to copy part of that message?

Looking at write_msg_parser and write_validate_container why this is
not just
want_mem_size = not message.has_attr("nocopy")
? I tried and just fix parse_msgc_smartcard_reader_add, as expected.

Fine (beside the missing ";") but I would add some comments here (before the @ifdef like maybe?)
/* The protocol specification for SmartcardChannel is broken and not
* working:
* - different messages have the same ID causing some message definition
* to be ignored;
* - the structure of the resulting message is not the same used by
