This was mostly boilerplate conversion, but in one case I needed to
define several differently named char* to take the place of a single
char *tmp that was re-used multiple times, and in another place there
was a single char* that was used at the toplevel of the function, and
then later used repeatedly inside a for loop, so I defined a new
separate char* inside the loop.

This should be applied on top of Dan's IPv6 NAT patch series (it was
reviewing that series that showed me this file hadn't yet been
converted).
