    Windows: DirOpenReferenceCount reorganizing completed
    
    This patchset completes the reorganizing of the DirOpenReferenceCount
    handling.  Now that every AFSCcb is given a refCount in AFSInitCcb()
    which is released in AFSRemoveCcb() it is possible to simplify some
    of the logic surrounding DirOpenReferenceCount handling across
    the AFSCommonCreate -> XXX -> AFSLocateNameEntry -> {MountPoint, Symlink}
    call sequences.
    
    Wherever possible releasing of DirOpenReferenceCounts occur in a
    functions try_exit block.  AFSCommonCreate() uses the new variables
    bReleaseDir and bReleaseParentDir to track whether these refcounts
    need to be released.  Additional comments document the decision
    making.
    
    There was at least one code path in AFSLocateNameEntry() where
    the DirOpenReferenceCount could be dropped when it should not have
    been. (pExistingDirNode == pDirNode).
