Provide IOC flags for Windows fs attributes so that they can be retrieved (or
even altered) using the FS_IOC_[GS]ETFLAGS ioctl and read using statxat().

If you're adding FAT specific flags here into the generic xstat
interface, can we get a bunch of common XFS specific flags into this
interface as well so people don't need to use xfs_io to get/set
them?

Cheers,

Dave.
