c0458999f9 SummingSortedBlockInputStream: fix summing of multiple blocks
Previously the destination columns were only computed for the first
block, so that subsequently written blocks failed to write
aggregation results to corrent columns.

e936c4d066 AggregateFunctionSum: implemented sumWithOverflow(x)
By default sum(x) promotes the result type to
largest possible integral type to avoid
arithmetic overflow when summing values from
smaller data types.

This is generally desirable behaviour, but it doesn’t
work with summing merge tree, as the result is
expected to be of same type as the input.

5c87a91aaf SummingSortedBlockInputStream: fix explicitly configured columns to sum
This fixes a variant of SummingMergeTree() in which
the columns to sum are explicitly configured.
Previously columns not in that list were ignored,
instead of writing last value.

This also fixes summation of invalid maps with
with only one key column and no value columns.

Modified test to work around compaction limitation
in which a zero-value column isn’t compacted
immediately if the inputs are non-zero but the
output is zero (+1 -1).

2edf5492d0 AggregateFunctionSumMap: support variardic arguments, specialized keys
The function is rewritten to avoid allocations on every insert with
Field deserialising each array. The key type is now specialized,
so it can be accessed directly. The value type is variant type,
but only individual values are deserialised (which is cheap, since they're PODs).
The function also support summing of multiple columns by the same key.

The SummingSortedBlockInputStream uses the function in case of
Nested structure with one numeric key and many values to sum.

c09a43a7b2 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.
