Summary: added support for remembering input file positions
Keywords: 

	* configure.in: added LARGEFILE_SOURCE & FILE_OFFSET_BITS to
	CPPFLAGS, export localstatedir to syslog-ng,

	* src/affile.c (affile_sd_format_persist_name): new function,
	formats the persistent name associated with the file source,
	(affile_sd_init): check if the current file position is available
	and set it if it is,
	(affile_sd_deinit): save the current file position,

	* src/afsocket.c (afsocket_sd_kill_connection_list): new function,
	frees a connection list, 
 	(afsocket_sd_deinit): fixed a possible SIGSEGV, a GList was freed as
	an AFSocketSourceDriver, I wonder how this got unnoticed so far,
	
	* src/cfg.c (persist_config_add_entry): new function,
	(persist_config_add): use the new add_entry function,
	(persist_config_add_survivor): new function, adds a surviving entry,
	(PersistentConfig): added saving/loading persistent config entries,

	* src/logreader.c (log_reader_watch_new): don't seek the file to the
	end-of-file now as proper file position is recovered,
	(log_reader_set_pos, log_reader_get_pos): new functions

	* src/main.c (main): added --ignore-persistent option, use a
	persistent configuration object around stop/start to save/restore
	file position information
