One less global variable, and it does only matter with migration.

We keep the old "--only-migratable" option, but also now we support:

Hmm, now vl.c has no way to access migrate_get_current(). Export a
function for it to setup only_migratable.

migration: let MigrationState be a qdev

Let the old man "MigrationState" join the object family. Direct benefit
is that we can start to use all the property features derived from
current QDev, like: HW_COMPAT_* bits, command line setup for migration
parameters (so will never need to set them up each time using HMP/QMP,
this is really, really attractive for test writters), etc.

I see no reason to disallow this happen yet. So let's start from this
one, to see whether it would be anything good.

Now we init the MigrationState struct statically in main() to make sure
it's initialized after global properties are applied, since we'll use
them during creation of the object.

No functional change at all.
