Possibly. It would be a separate patch, but I can add it.
The question is just where to move query-iothreads. Do we have a good
place, or do I need to separate misc.json and a new misc-sysemu.json?

"Make sure"?
I think the order of the generation doesn't matter because generating
the storage daemon files doesn't actually access the main ones.
Generated C files shouldn't be a problem either because if we link an
object file into a binary, we have a make dependency for it.
Maybe the only a bit trickier question is whether we have the
dependencies right so that qemu-storage-daemon.c is only built after the
header files of both the main schema and the specific one have been
generated. If I understand the Makefile correctly, generated-files-y
takes care of this, and this patch adds all new header files to it if I
didn't miss any.
