Add VFS2 support for device special files.
- Add FileDescriptionOptions.UseDentryMetadata, which reduces the amount of
boilerplate needed for device FDs and the like between filesystems.
- Switch back to having FileDescription.Init() take references on the Mount and
Dentry; otherwise managing refcounts around failed calls to
OpenDeviceSpecialFile() / Device.Open() is tricky.
