Peter Maydell e80b4b8fb6 VFIO updates 2016-10-31 
- Replace skip_dump with ram_device to denote device memory and mark
    as non-direct to avoid memcpy to MMIO - fixes RTL (Alex Williamson)
  - Skip zero-length sparse mmaps - avoids unnecessary warning
    (Alex Williamson)
  - Clear BARs on reset so guest doesn't assume programming on return
    from S3 (Ido Yariv)
  - Enable sub-page MMIO mmaps - performance improvement for devices
    with smaller BARs, iff both host and guest map them to full,
    aligned pages (Yongji Xie)
