Chaining classmethod descriptors (introduced in bpo-19072) is deprecated. It
can no longer be used to wrap other descriptors such as property(). The
core design of this feature was flawed, and it caused a number of downstream
problems.

Add a closure keyword-only parameter to exec(). It can only be specified
when exec-ing a code object that uses free variables. When specified, it
must be a tuple, with exactly the number of cell variables referenced by the
code object. closure has a default value of None, and it must be None if the
code object doesn't refer to any free variables.

Fix a crash in subinterpreters related to the garbage collector. When a
subinterpreter is deleted, untrack all objects tracked by its GC. To prevent
a crash in deallocator functions expecting objects to be tracked by the GC,
leak a strong reference to these objects on purpose, so they are never
deleted and their deallocator functions are not called. Patch by Victor
Stinner.

ctypes used to mishandle ``void`` return types, so that for instance a
function declared like ``ctypes.CFUNCTYPE(None, ctypes.c_int)`` would be

targets require function pointers to be called with the correct signatures
so this led to crashes. The problem is now fixed.
