e373862c83 Do not use more then 98K of memory for uniqCombined* 
uniqCombined() uses hashtable for medium cardinality, and since
HashTable resize by the power of 2 (well actually HashTableGrower grows
double by the power of 2, hence HashTableGrower::increaseSize() should
be overwritten to change this), with 1<<13 (default for uniqCombined)
and UInt64 HashValueType, the HashTable will takes:

  getBufferSizeInBytes() == 131072

While it should be not greater then sizeof(HLL) ~= 98K, so reduce the
maximum cardinality for hashtable to 1<<12 with UInt64 HashValueType and
to 1<13 with UInt32, overwrite HashTableGrower::increaseSize() and cover
this using max_memory_usage.

f46c5a47c0 Introduce uniqCombined64() to get sane results for cardinality > UINT_MAX 
By default uniqCombined() uses 32-bit hash for all types except String,
so this means that you cannot use uniqCombined() with i.e UInt64 and
cardinality > UINT_MAX, although you can use uniqCombined(toString())
and this will lead to 64-bit hash, but will not have good performance.

So uniqCombined64() had been introduced to fix this.

Requires: #7213

92c88248a1 Fix uniqCombined() result for >UINT_MAX values (return UInt64 to avoid overflow) 
uniqCombined() return type is UInt64, but uniqCombined() uses
CombinedCardinalityEstimator, and CombinedCardinalityEstimator::size()
return type is UInt32, while the underlying HyperLogLog::size() is
UInt64.

So after this patch uniqCombined() can be used for >UINT_MAX values, the
outcome is not ideal (#2073) but at least sane.

367c537106 Do not include Field.h everywhere through SettingsCommon.h. 
Move the methods of SettingsCollection<> that are dependent on Field to
a separate file, and include it once for each instantiation. This allows
to work on Field without always recompiling the entire project.
