[lumberjack] Implementation-filled fields in https://fedorahosted.org/lumberjack/wiki/FieldList

[Miloslav Trmač]

Hello,
when discussing a lumberjack-enabling patch set, it was pointed out that [ugp]id fields
should be filled based on SCM_RIGHTS - and the Fedora configuration we are considering
actually does that.

Both rsyslog's imuxsock and libumberlog add the following fields:
* pid
* uid
* gid
(and each adds some other fields that the other does not).

Is there a consensus to mark these three as "to be filled by log implementation, not
by applications?  If so, I'll go ahead and edit the wiki.

Thank you,
    Mirek
