MFC r269497:

Add support for Windows dialect of EXTENDED COPY command, aka Microsoft ODX.

This allows to avoid extra network traffic when copying files on NTFS iSCSI
disks within one storage host by drag'n'dropping them in Windows Explorer
of Windows 8/2012.  It should also accelerate Hyper-V VM operations, etc.
