[svn-r14863] Checking in code supporting metadata journaling in the serial case.
While this code doesn't break any of the existing tests, it HAS NOT
been tested beyond that.
Also mods needed to integrate the journaling code with Quincey's latest
mods, and to adapt existing test code to slight changes caused by the
addition of journaling.
Finally, fixed an undefined variable bug in the HL code exposed by the
journaling mods.
Tested serial under Linux (Phoenix) and parallel under Linux (Kagiso).
