Instead of be limited just by the size of addressable memory (2**63 bytes), Python integers are now also limited by the number of bits, so the number of bit now always fit in 64-bit integer. Both limits are much larger than what can be available on practice, so there is no effect on users. _PyLong_NumBits() and _PyLong_Frexp() are now always successful.
