[PATCH v3 00/17] hw/9pfs: Add 9pfs support for Windows

[Bin Meng]

At present there is no Windows support for 9p file system.
This series adds initial Windows support for 9p file system.

'local' file system backend driver is supported on Windows,
including open, read, write, close, rename, remove, etc.
All security models are supported. The mapped (mapped-xattr)
security model is implemented using NTFS Alternate Data Stream
(ADS) so the 9p export path shall be on an NTFS partition.

'synth' driver is adapted for Windows too so that we can now
run qtests on Windows for 9p related regression testing.

Example command line to test:

  "-fsdev local,path=c:\msys64,security_model=mapped,id=p9 -device 
virtio-9p-pci,fsdev=p9,mount_tag=p9fs"
