Description

    journald: Support writing new records
    
    This change adds ability to report new messages in the journal log.
    This is done by the LMI_JournalLogRecord.CreateInstance() method call
    taking only CreationClassName, LogCreationClassName, LogName and DataFormat
    key properties as mandatory, with no need to specify the MessageTimestamp and
    RecordID key properties. The returned instance will contain all the
    information with actual RecordID key property of the new record.
    
    As long as sd_journal_send() actually only queues the request, we need
    to watch for journal changes in order to find the new record. This is
    quite unfortunate as the daemon could be busy and we can't wait forever.
    Messages are available immediately usually, a timeout is set to 5 seconds
    for the moment.
    
    Record matching is done by comparing the message itself, the origin function
    name and PID. This brings sufficient amount of confidence though more
    sophisticated approach may be needed in future to ensure fiull uniqueness.
