Maciej S. Szmigiero	4e55cb3cde	migration: Add MIG_CMD_SWITCHOVER_START and its load handler ... This QEMU_VM_COMMAND sub-command and its switchover_start SaveVMHandler is used to mark the switchover point in main migration stream. It can be used to inform the destination that all pre-switchover main migration stream data has been sent/received so it can start to process post-switchover data that it might have received via other migration channels like the multifd ones. Add also the relevant MigrationState bit stream compatibility property and its hw_compat entry.

Steve Sistare	f3bff6c443	migration: export fewer options ... A small number of migration options are accessed by migration clients, but to see them clients must include all of options.h, which is mostly for migration core code. migrate_mode() in particular will be needed by multiple clients. Refactor the option declarations so clients can see the necessary few via misc.h, which already exports a portion of the client API.
