Do not use more then 98K of memory for uniqCombined*

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.

f3bde19b74 Do not use iterators in find() and emplace() methods of hash tables. 
Instead, these methods return a pointer to the required data as they are
stored inside the hash table. The caller uses overloaded functions to
get the key and "mapped" values from this pointer. Such an interface
avoids the need for constructing iterator-like wrapper objects, which is
especially important for compound hash tables such as the future
StringHashMap.

cacf6d3282 Key memory management for compound hash tables. 
Some aggregation methods initially emplace a temporary StringRef key
into a hash table. Then, if the key was not seen before, they make a
persistent copy of the key and update the hash table with it. This
approach is not suitable for compound hash tables, because the logic of
when the persistent key is needed is more complex, and is contained
within the hash table itself.

In this commit, we switch to managing key memory with callbacks passed
to the hash table, that allow it to request a persistent copy of the key
if it is needed. This should be more appropriate for compound hash
tables.

This commit prepares for StringHashMap PR #5417.

a719933c58 Fix initial size of some inline PODArray's. 
A template parameter of PODArray named INITIAL_SIZE didn't make its
units clear, which made some callers to erroneously assume that it
specifies the number of elements and not the number of bytes.
Rename it, fix the wrong usages and, where possible, use the
PODArrayWithStackMemory typedef for arrays with inline memory.
