We don't need any special handling for them on the client, and, on the
contrary, have to handle them as logical errors in tests.

Assert that allocator & container are consistent wrt. inline memory
...
There are lots of places where HashTable is used with
AllocatorWithStackMemory, but the size of allocator inline memory is set
incorrectly, and it's less than the initial HashTable buffer size.
Because of this, HashTable is always allocated on the heap, and the
inline memory becomes a useless dead weight.
For PODArray, we have previously added a helper template that makes sure
these values are in sync, so there was only one such discrepancy left,
in the unit test.

Fix serialize/deserialize of denominator of Average functions
...
Use writeBinary/readBinary to serialize/deserialize the denominator of Average functions.
Previously it would be transmitted as an unsigned int, which means its value would get corrupted when doing an avgWeighted over a floating point number.
Note: this commit is not backwards compatible!
