#2258 log: add alternative destinations of log records

[Vu Minh Nguyen]

The log service is as is dedicated to writing log records to file and this has so far been the only destination for log records. Several attributes in the configuration object and log stream objects are dedicated for configuration of this file handling. This is legacy.

Now, we introduce a generic way of handling alternative destinations of log records. Legacy handling of log records will not be changed.

Find more information in attachement.

The PRI field of the message ought to be filled in with a severity taken from the SaLogSeverityT field in the SAF log message header, and some appropriate facility (probably 16 - "local use 0").

The STRUCTURED-DATA field should countain a meta sequenceId parameter containing a sequence number of each message, so that it is possible to detect message loss.

The MSGID should contain a hash of the log stream name.

An increment implementing support for the new configuration attributes 'logRecordDestinationConfiguration' and 'logRecordDestinationStatus' (only OpenSafLogCurrentConfig class) is sent for review by the community.
Will be pushed separately when acked

[Vu Minh Nguyen]
