    Windows: Check Avail Space on extending SetEndOfFile
    
    When cm_SetLength() is called with an extending file length,
    check the available free space in the volume to see if the
    new length will fit.  If not, return CM_ERROR_SPACE.
    
    This permits applications to discover that there is insufficient
    space prior to writing all of the data into the windows page
    cache at which point it will be too late.
    
    There is still the possibility of a race that can result in
    data loss if two applications are writing into the same volume
    at the same time and there is insufficient room.
