Just a high-level glance through, and not a thorough review.
The command line approach here looks reasonable, although it might be
easier to add the QAPI types first (patch 4/5) and then use that type in
this patch, instead of open-coding things.

Is it still legally open source if you reserve all rights, or does this
statement contradict the rest of your header? (Not that you are the
first person to attempt this; the phrase "All rights reserved" appears
in a number of other files in qemu.git, including the mis-spelled
disas/libvixl/LICENCE)

Coding style - indent by 4 spaces, not 8.

Please don't name internal functions with leading __ - that namespace is
reserved for the compiler and libc.
