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 text data bss dec hex filename - 514963 2727 15396 533086 8225e lib/libuClibc-0.9.30-svn.so + 514888 2727 15396 533011 82213 lib/libuClibc-0.9.30-svn.so
