gh-129149: Add fast path for medium-sized integers in `PyLong_FromSsize_t()` ( #129301 )
...
The implementation of `PyLong_FromLong()`, `PyLong_FromLongLong()` and `PyLong_FromSsize_t()`
are now handled by a common macro `PYLONG_FROM_INT` which contains fast paths depending on the
size of the integer to convert. Consequently, `PyLong_FromSsize_t()` for medium-sized integers is faster
by roughly 25%.

gh-111140: Improve PyLong_AsNativeBytes API doc example & improve the test ( #115380 )
...
This expands the examples to cover both realistic use cases for the API.
I noticed thing in the test that could be done better so I added those as well: We need to guarantee that all bytes of the result are overwritten and that too many are not written. Tests now pre-fills the result with data in order to ensure that.
