* remotes/amit-migration/tags/mig-2.3-1:
  vmstate: type-check sub-arrays
  migration_cancel: shutdown migration socket
  Handle bi-directional communication for fd migration
  socket shutdown
  Tests: QEMUSizedBuffer/QEMUBuffer
  QEMUSizedBuffer: only free qsb that qemu_bufopen allocated
  xbzrle: rebuild the cache_is_cached function
  xbzrle: optimize XBZRLE to decrease the cache misses
