DataStreams/SummingSortedBlockInputStream: use builtin aggregated functions
...
This replaces custom summation function implementations with an implementation
using built-in aggregation functions (sum and sumMap). The goal is to be able to
use specialized variants of aggregation functions, and to have a single
efficient implementation.
