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.

fa098b469c AggregateFunctionSumMap: compact keys with zero value 
This allows `sumMap(k, v)` to compact all keys
for which the values are all zero.

70543200be 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.

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.

* AggregateFunctionTopK generic variant deserialises
  it as well instead of ignoring it
* AggregateFunctionTopK generic variant clears the
  array before deserialising
