Third round of eliminating allocations in the MongoDB driver. See #633.
Fourth round of eliminating allocations in the MongoDB driver. See #633.

MongoCollection.find[One] now accepts an explicit return type instead of always returning Bson. This allows to avoid all memory allocations as long as the return type doesn't contain indirections (e.g. strings or arrays).
Use uninitialized buffers for Bson serialization. See #633.
Fix the simple overloads of MongoCollection.find with a non-Bson return type.
Assert !empty in MongoCursorData.popFront and remove the assertion in MongoCursorData.index.
Add simple benchmarks for URLRouter and the MongoDB driver.
Fix log message ("handle" vs. "send").
