This series introduces a new generic function strtolower(), which converts strings to lowercase in-place, overwriting the original string. This kind of functionality is needed in several places in the kernel. Right now, everybody seems to be implementing their own copy of this function. So, we replace several custom "strtolower" implementations with this new library function. Another

as the next klibc release 1.5.16 looks like shaping up, I have a trouble to build that for Debian. currently I build depent on linux-libc-dev, I don't know what against I can build latest klibc, see klibc fails to build due too: make -C linux/ ARCH=x86_64 INSTALL_HDR_PATH=debian/tmp/usr/lib/klibc/ headers_install make[3]: *** No rule to make target `headers_install'. Stop. make[2]: ***
