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.

SpaceSaving: internal storage for StringRef{}
...
The SpaceSaving has now specialised storage for
some keys, which only copies keys that
are to be retained in the structure, not all.
Most of the PODs implement this interface empty,
so there shouldn’t be any extra cost.

AggregateFunctionTopK: fix memory usage, performance
...
* allow separate table key / hash key, and use
std::string / StringRef for generic variant as
it has built-in storage and StringRef is supported
by the hash table, this avoids infinitely
growing arena with serialised keys
* use power-of-2 size for alpha vector for faster
binning without using modulo
* use custom grower and allocator for SpaceSaving
to start with smaller tables
* store computed hash in counter for faster
reinsertion of smallest element
