    rpc.idmap: Hide global symbols from libidmap plugins
    
    This patch limits the visibility of the symbols in the nfs-utils
    conffile.c so that they are only visible to programs linked directly to
    it.  This forces the objects dynamically loaded via libnfsidmap to use
    the functions defined in that shared library instead.
