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.

dbms: Fix build with clang after Poco update
...
In the current version of Poco, unsigned long no longer aliases to
UInt64 with LP64. The size_t aliases to unsigned long with clang,
so all the uses of size_t instead of UInt64 when interacting with
Poco interfaces are gone. I replaced uses with UInt64 where it makes
sense, and added an overloaded function for readVarUInt() to support size_t.

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.
