Access to live limit_conn values?

[bryndole]

Our own investigation indicates that, no, there is not way to directly
access the values in the limit_conn zones from "user space."

We created a new status page that reports all the existing zones and the
current connection counts for each, as well as what the current limits are.
It does this by walking the config data structure and building a list of the
zones and then creating a simple report page.
