[issue28988] Switch dict and set structures to PyVarObject

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

In issue28959 Raymond said that a dict structure can be switched to PyVarObject. Victor guessed that it makes sense to switch a set structure too. Proposed patch implements this. The layout of a dict structure is not changed. The number of used and filled entries in a set structure are swapped, therefore extensions that use PySet_GET_SIZE or access fields of PySetObject directly (both are not in a stable API) should be recompiled.

I don't see a benefit from this patch except some unification.
