Hi,

To my surprise, QEMU didn't seem to check that required migration entries and
subsections are loaded. I took a naive approach to add such check, by adding
some "visited" marks along the loading path, and checking by the end that all
required entries have been loaded.

Note, I haven't thoroughly tested it yet (it passed make check on x86 targets
with the preliminary "fixes" applied).

Comments welcome!

First 3 patches are bug fixes, am I right?

It'll be great if they can be acked (or even picked up earlier?) by
subsystem maintainers if so, and copy stable if justified proper.

Thanks,
