From 01ffe8e2f4ca24325e81f040e1ac3a5a17afa5d5 Mon Sep 17 00:00:00 2001

Subject: [PATCH] config: Move any_client_port_set() to config.c

This functions is now used outside of networkstatus.c and makes more sense to
be in config.c.

It is also renamed to options_any_client_port_set() for the config.c
namespace.

No code behavior change.
