libc: port FreeBSD string library routines

Browse Source 
Oh my fucking god this was by far the most awful
and boring and tedious day in my entire life.

Also, dear FreeBSD people: please don't sue me.
I tried really hard to comply with all the
copyright stuff, but it is absolutely possible i
made a mistake.  Just DM me and i'll do everything
in my power to fix it, even if that means
releasing entire portions of GayBSD under the BSD
license.  I don't care, i just want stuff to work.

(i'm including this message to use it as possible
evidence in case i get sued to show my good will)
