IPv6 userland cleanup

[Mihir Luthra]

Hi everyone,

I have started working on the project ipv6 userland cleanup [1]. I
introduced myself here almost 2 months [2] ago but couln't really start
with project before due to time constraints. Now I started with replacing
some gethostby* calls with getaddrinfo(3).
I have some code with me which I want to submit for reviewing.
I had created an account on phabricator. Can it be approved by someone?

Also, while replacing gethostby* calls, I came across arp. I learned that
arp command is only for ipv4 while ipv6 uses ndp protocol. I was wondering
if it would be useful to make a ndp command for ipv6 just like arp is for
ipv4?
