Some possible additions to the DM ioctl patch for strace

Hello.

I've took the liberty to look at the patch and I'd like to propose some changes to it. Can you please review them from the DM side of things? I'm not quite sure I've understood all the specifics of the interface correctly, it's quite peculiar.

I'm also preparing a patch for the DM ioctl decoder test, but it's not ready yet.
