General

Added an optimization to the execution of aggregation pipelines that greatly speeds up all range queries done for aggregations. (#802)

In TokuMX 1.3.2 and earlier, part of the oplog trimming process (an optimization step) tended to hold a read lock for long periods of time. Now in 1.3.3, this component works in 4-second periods, which is configurable with the parameter optimizeOplogQuantum, which can be set dynamically with setParameter. (#777)

Valid values are:
- N > 0: Work in periods of N seconds.
- N = 0: Do not optimize the oplog at all.
- N < 0: The 1.3.2 behavior, optimize aggressively without yielding.
Removed an unnecessary step in a replica set secondary's startup process that had the potential to cause long stalls and pileups. (#806)
Certain query operations sometimes spend a long time in the storage layer, searching through entries that were deleted but not garbage collected. Added a mechanism by which such operations can be killed like normal operations. (#813)
Fixed a memory allocation size issue that could cause crashes when dealing with very large leaf entries. (#822)
