Bugfix with the way data was copied out to static buffers.
Now (again) copies to cursor's temp storage if it is not a temporary cursor
if it is a db handle call, or a temporary cursor, it will use the db's temporary storage.

The file size is a larger, but the logs are a lot smaller.

Addresses #725, #775.

Manipulations:
{{{
$ (cd tokudb; svn merge -r3763:3778 https://svn.tokutek.com/tokudb/tokudb.725)
$ svn delete tokudb.725
}}}

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.


git-svn-id: file:///svn/tokudb@3764 c7de825b-a66e-492c-adef-691d508d4ae1

Increment {{{layout_version}}} to 6.
brtdump now has a {{{--nodata}}} option (to print only the metadata, but not the data)
Fixes #766.

cd tokudb/tokudb
svn merge -r3713:3725 https://svn.tokutek.com/tokudb/tokudb.766
