Summary: fixed possible segmentation fault on SIGHUP
Keywords: 

	* src/afsocket.c (afsocket_sc_set_owner): new function, changes all
	references to a new AFSocketSourceDriver (this happens accross
	SIGHUPs),
	(afsocket_sd_set_listener_keep_alive): removed, there's no separate
	LISTENER_KEEP_ALIVE setting,
	(afsocket_sd_init): instead of simply changing the next-hop log-pipe
	of connections call afsocket_sc_set_owner which changes less
	explicit references

	* src/cfg-grammar.y (yyparser_reset): new function, resets all
        'last_' variables as they are not referenced and might contain
        pointers to stale data

	* src/logpipe.c (log_pipe_free_instance): function body moved to
	log_pipe_unref to clear some clutter in backtraces and both
	functions are only a couple of lines anyway

	* src/logreader.c (log_reader_set_options): new function, allows the
	caller to change the pointer to the options structure
