	    * bus/main.c (signal_handler): Reload the configuration files
	    on SIGHUP.
	    (main): Set up our SIGHUP handler.

	    * bus/bus.c (struct BusContext): Store the config file, user and
	    fork flag in the BusContext.
	    (process_config_first_time_only): Added.  Contains the code
	    (previously in bus_context_new) for setting up the BusContext from
	    the BusConfigParser that should only be run the first time the
	    config files are read.
	    (process_config_every_time): Added.  Contains the code (previously
	    in bus_context_new) for setting up the BusContext from the
	    BusConfigParser that should be run every time the config files are
	    read.
	    (load_config): Added.  Builds a BusConfigParser from the config
	    files and passes the resulting structure off to
	    process_config_first_time_only (assuming this is the first time)
	    and process_config_every_time.
	    (bus_context_new): All of the config-related code has been moved
	    to process_config_first_time_only and process_config_every_time.
	    Now this function just does the non-config-related initializations
	    and calls load_config.
	    (bus_context_reload_config): Added.
