add unique_checks option to db-benchmark-test to show the excessive splitting and merging bug. addresses #1828

Merge 1781 back to main line. Closes #1781 (since #1781 involves creating a test.) There is a bug exposed by the x2.tdb test, but actually making the x2 test run right is a separate issue (Refs #1823).

I thought that the merge was implicated for making nodes too big, but now I'm convinced it's not.

When the brt tries to merge two nodes (maybe_merge_pinned_leaf_nodes) it has two cases
 1) The nodes combined are more than 3/4 a node, in which case it balances the nodes.
 2) Otherwise it merges them.  Hence merged nodes are always smaller than a node.

So I'm considering #1802 and #1811 to be fully resolved.

Refs #1802.  Closes #1811
