Switch from normal migration loadvm process into COLO checkpoint process if COLO mode is enabled. We add three new members to struct MigrationIncomingState, 'have_colo_incoming_thread' and 'colo_incoming_thread' record the COLO related thread for secondary VM, 'migration_incoming_co' records the original migration incoming coroutine.

Add a new migration state: MIGRATION_STATUS_COLO. Migration source side enters this state after the first live migration successfully finished if COLO is enabled by command 'migrate_set_capability x-colo on'. We reuse migration thread, so the process of checkpointing will be handled in migration thread.

We add helper function colo_supported() to indicate whether colo is supported or not, with which we use to control whether or not showing 'x-colo' string to users, they can use qmp command 'query-migrate-capabilities' or hmp command 'info migrate_capabilities' to learn if colo is supported. The default value for COLO (COarse-Grain LOck Stepping) is disabled.
