Prepare for an index or range scan

Registered by rich prohaska on 2013-10-31

The prepare index scan patch notifies the storage engine that a full index scan is imminent.
The prepare range scan patch notifies the storage engine that a range query is imminent.
This gives tokudb the opportunity to do prelocking which speeds up the scans.
