    [PATCH] kconfig: make sym_change_count static, let it be altered by 2 
functions only
    
    Those two functions are
        void sym_set_change_count(int count)
    and
        void sym_add_change_count(int count)
    
    All write accesses to sym_change_count are replaced by calls to above
    functions.
    
    Variable and changer-functions are moved to confdata.c.  IMO thats ok, as
    sym_change_count is an attribute of the .config's change state.
