    Don't pass more than G_MAXSSIZE bytes at once to write() in glib/gfileutils.c
    
    Behaviour in that case is implementation-defined and how many bytes were
    actually written can't be expressed by the return value anymore.
    
    Instead do a short write of G_MAXSSIZE bytes and let the existing loop
    for handling short writes takes care of the remaining length.
