Add a config_mgr_t type to wrap config_format_t

Browse Source 
Remember that our goal in the present refactoring is to allow each
subsystem to declare its own configuration structure and
variables.  To do this, each module will get its own
config_format_t, and so we'll want a different structure that wraps
several config_format_t objects.  This is a "config_mgr_t".
