Subject: [PATCH 3/3] server-info: clean up after writing info/packs

From: Jeff King <[email-masked]>
Date: Sat, 13 Sep 2014 16:19:38 -0400

We allocate pack information in a static global list but
never clean it up. This leaks memory, and means that calling
update_server_info twice will generate a buggy file (it will
have duplicate entries).
