…p_flags

It is now allowed to add new fields at the end of the PyTypeObject struct
(and even in the middle, if we are so inclined) in feature releases without
having to allocate a dedicated compatibility flag in tp_flags.

This will reduce the risk of running out of bits in the 32-bit tp_flags value.
