[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.
