Revision 75298

Primordial : was the 'stuff' that RuntimeInstance did pre-init to catch
log messages.  By having this Primordial logger, we can remove that stuff
from RuntimeInstance, and better, remove the if() to make it a touch
speedier.  Suggested by Carsten and Jeroen (I thinK).

Null : do-nothing logger - created in the event of LogManager failure
to keep things going - also can be used as a bit-bucket logger.
