    Windows: Enforce Share Access
    
    Use file server locks to enforce file share access modes
    via the afs redirector interface.  The approach taken
    integrates share mode enforcement with the file server
    lock tracking code in the service.  The share mode
    enforcement mimics that of the SMB Server interface.
    
    This patchset includes two functional changes to
    the previous locking and share mode processing:
    
     1. The cm_scache_t fsLockCount field is used to
        determine if the desired lock can be granted
        by the file server.  If not, the RXAFS_SetLock()
        request is skipped and the request is failed
        locally.
    
     2. cm_CheckNTOpen() now accepts the desired and
        and share access modes.  The share access mode
        is used to determine if a test lock should be
        obtained at all.  If the share mode is FILE_SHARE_WRITE
        then no lock is requested.  This change permits
        Microsoft Office applications to offer the user
        the ability to open the file in read-only mode
        and notify the user when the document can be
        opened in read-write mode.
