[Samba 4] Default logging format isn't optimal

[Matthias Dieter Wallnöfer]

Hi all!

I noticed in bugzilla someone who writes, that the logging format in 
SAMBA 4 isn't such good.

The default logging format is kind of sucky right now. The main issue is that
each event is spread across two lines.

If you grep through a log file for a user ID, hostname, or share name you find
it, but since the date and time are on a different line you can't co-ordinate
events easily. At the very least each event should be on one line.

Since 4.x is changing so many other things, a small tweek to the logging format
to help out sysadmins (and their monitoring tools) should at least be
considered.

So abartlet and I thought to discuss a little bit about this. I haven't 
a preference on that. Maybe you?
