refs #54 , improve the performance of hot indexing. This change does two things:
...
- gets indexer to run in reverse, that is, start at the end and run to beginning
- refines locking a bit. An estimate of the position of the hot indexer is stored,
that is cheap to look at. Threads that use this estimate with a mutex either do
only a quick comparison or set it to a new value. Threads doing writes (with XXX_multiple calls)
will check their position with respect to the estimate, and if they see the hot indexer
is already past where they will modify, they don't grab the more expensive indexer
lock. For insertion workloads that go to the end of the main dictionary of a table/collection,
this check should practically always pass.

#refs 5133 merge undo-do algorithm changes to main. now, we read a row from the source db AND gather up the leaf entrie's provisional data in the cursor callback, which makes it atomic with respect to commit and abort on that DB. had to fix a few tests after changing some leaf entry signatures

close[t:5134] le_cursor api cleaned up, followed up on a TODO to get rid of the DB parameter from is_key_right (and improved its name too) by using a fake_db in the le_cursor plus the new toku_ft_get_descriptor() api to grab a descriptor reference. refactored some tests to get it all compiling. LE and hot indexer tests pass
