Changed CLR log format so that it is identical to update entries. The old format pointed back to an earlier
...
entry in the log, complicating truncation significantly. The new format copies log entries into their CLRs,
and is somewhat redundant, as redo and undo information is stored in the CLR, but the undo information will
never be used...
