Hello Everyone,
Here are some cleanups around the colo migration code. Notably, we only
support the same qemu version on both sides for now. Though in this
patchset I still try to be support migration to a newer qemu version.

Lukas Straub (8):
  colo: Only support the same qemu version on source and destination
  colo: Setup ram cache in normal migration path
  colo: Replace migration_incoming_colo_enabled() with migrate_colo()
  colo: Remove ENABLE_COLO loadvm command functions
  colo: Don't send ENABLE_COLO command
  colo: Reject colo with postcopy capability enabled
  colo: Reject colo with block migration capability enabled
  ram: Remove useless colo special-casing
