So this is why you need a new command-line option.
I think we need a generic mechanism for post-initialization of whatever
is given on the command line. Perhaps you can do that with an
interface, and get rid of -memdev and memdev_add altogether?
MemoryBackend's implementation of the interface's sole method would call
get_memory, of course.
