This massive patch brings support for parsing incoming syslog messages, remote or local, to determine if format is RFC5424 or the older RFC3164. For logging syslogd currently defaults to RFC3164 for local files and supports RFC5424 for sending to remote servers. Signed-off-by: Joachim Nilsson <troglobit@gmail.com>
