ctype: remove some trivial macros from ctype.h;

 remove __tolower and __toupper (they existed only in SOME configs!);
 remove usages of _tolower (some of them clearly buggy) from uclibc code;
 add a few more -U<define> options to unifdef pass over installed headers;
 document it on docs/wchar_and_locale.txt
