CheckResults: start hiding .data, first step to clean it up

The goal is to make CheckResults more strongly typed, and remove the
ambiguous ".data" field in favor of a bunch of specific counters and
sharelists, so I can changes .sharemap and .servermap to use IServer
instances instead of string serverids. By cleaning this up first, I hope
to get that task done with less debugging.
