[Qemu-devel] [PATCH v3 14/29] migration: Move the VMStateDescription typedef to typedefs.h

[Markus Armbruster <armbru@redhat.com>]

We declare incomplete struct VMStateDescription in a couple of places
so we don't have to include migration/vmstate.h for the typedef.
That's fine with me.  However, the next commit will drop
migration/vmstate.h from a massive number of compiles.  Move the
typedef to qemu/typedefs.h now, so I don't have to insert struct in
front of VMStateDescription all over the place then.
