    Windows: AFSVolSync creationDate based readonly volume versioning
    
    Implement readonly volume versioning based upon the .readonly
    volume creation date as reported in the AFSVolSync output
    parameter of every RXAFS RPC.
    
    Whenever a new callback is obtained for an object stored within
    a .readonly volume, the volume creation date is recorded in the
    cm_volume object along with the callback expiration time and
    a reference to the server that issued it.  These values are
    used to determine if a callback is present when the cm_scache
    object's volume creation date matches the cm_volume object's
    volume creation date.  If there is no match, the cm_scache
    object's individual callback information is used to determine
    whether a callback has been registered.
    
    This mechansism ensures that the whole-volume callback issued
    in response to a RXAFS_FetchStatus request against a .readonly
    volume can be applied to all objects that are cached from the
    same version of the .readonly volume instance.
