Description

libc: Import OpenBSD's inet_net_{ntop,pton}

Our versions of these functions (originally taken from BIND) simply
don't work correctly for AF_INET6. These were removed from BIND itself
quite a while ago, but OpenBSD has made several fixes in the mean time,
so import their code.

Add tests for both functions.
