Currently each module that needs to collect statistics implements custom code to do so. This is cumbersome. Create a general purpose module for collecting and reporting statistics. Statistics are output in the log at detail level, but there are other uses they could be put to eventually. No new functionality is added. This is just a drop-in replacement for the current statistics, with the advantage of being more flexible. The new stats are slower because they involve a list lookup, but performance testing shows stats can be updated at about 40,000/ms which seems fast enough for our purposes.
