Hey all,

This patch adds some of the missing 9 section manpages, those were
included from https://github.com/0intro/plan9-contrib and not reviewed
around 9front's kernel functions and infra, but it should mostly be
accurate, i've at least not included stuff like kbdputc or ref which
are useless to us, but haven't reviewed the rest.

added: conf, devattach, dmainit, lock, newchan and qio
