  compilation error due to bug in savevm.c

Status in QEMU:
  Fix Released

Bug description:


  Add xbzrle_encode_buffer and xbzrle_decode_buffer functions
      For performance we are encoding long word at a time.
      For nzrun we use long-word-at-a-time NULL-detection tricks from strcmp():
      using ((lword - 0x0101010101010101) & (~lword) & 0x8080808080808080) test
      to find out if any byte in the long word is zero.
