 Before we can move on to #30866 and have the responsibility for
 configuration formats spread across modules, we need to have the confparse
 code able to handle multiple configuration objects and formats as if they
 were one.

 I'm going to do this by introducing a "configuration manager" type that
 knows about a bunch of config_format_t objects.  The configuration objects
 will be collected under a single top-level configuration object.  (This
 approach lets us keep backward compatibility with a lot of the existing
 options management code.)
