For testability, and to support the exchange of debug information across Forwarder and server, it is helpful to encapsulate all debug information on the instance object. This CL moves all state in the debug package into a new 'State' type, that is added as a field on the debug.Instance. While doing so, common functionality for object collections is factored out into the objset helper type. Also add two new debug object types: Client and Server. These aren't yet used, but will be in a later CL (and frankly it was easier to leave them in this CL than to more carefully rewrite history...).
