arc4random() is not part of POSIX, it seems to come from BSD. So if anything, it should go into libbsd, not libroot.

We have an implementation in the FreeBSD compatibility layer (for drivers only, not in libbsd), but it just calls random(). But we shouldn't be doing that.
A nice introduction about arc4random here (if you can survive comic sans + jpeg artifacts - thanks OpenBSD :/): http://www.openbsd.org/papers/hackfest2014-arc4random/index.html
It seems the OpenBSD implementation is designed with portability in mind so we could try to port it. There are some other functions to help with proper random number generation which would be nice to have, too.

arc4random introduced in hrev57247.
This needs some more details. What exactly is missing? RC4 support in some library? Which one?
