Ah that's a good idea.

One day it would nice if QEMU had a standardized debug logging macro
in qemu-common.h, so we could just turn on/off debugging per file
using

   #define ENABLE_DEBUG 1
   #include "qemu-common.h"

I guess adding the enum definition itself to QAPI would mean we
would get better introspection support when we solve QOM class
introspection of properties.
