The "bind9" client-side resolver code is intended to be a reference
implementation only, not to be used as production code.  I should
know, I wrote a fair bit of it.  :)

I'd just look at how the lightweight resolver daemon is called (using
lwres_getaddrinfo() for instance) and put that into libc.  I have
actually done this to some degree, and was getting forward and reverse
lookups from ping6, traceroute6, and ssh with ipv4/v6 support.
