migration: move only_migratable to MigrationState

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

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

  -global migration.only-migratable=true

Currently still keep the old interface.

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