Const-ify the arguments of str_tolower() and friends to suppress compile
warnings. Clean up various unneeded cruft that was left behind aftercreating those routines. Introduce some convenience functions str_tolower_zetc to eliminate tedious and error-prone double arguments in formatting.c.(Currently there seems no need to export the latter, but maybe reconsiderthis later.)
