Bradley C. Kuszmaul 77fe15598c Removed the undo information from the logs (to rely on the checkpoint to save a good copy in the log).
Also, don't record the fingerprint changes, since they can be recalculated independently.  (This is a biggy.  The fingerprints updates were half the log changes.)
We'll have to do something about the fingerprints of internal nodes, so some if may come back in some form.
Speeds up {{{db-benchmark-test-tokudb -x}}} from 17477/s to 25696/s, and reduces the size of the {{{bench.tokudb}}} directory (containing logs and data) from 3.3GB to 1.7GB for a 0.33GB datafile.

Manipulations as follows:
 (cd tokudb;svn merge -r3676:3763 https://svn.tokutek.com/tokudb/tokudb.740 )
 svn delete tokudb.740

Fixes #775.
