This commit is the result of copying the total_ordering code and tests
over from CPython v3.7.17.
One test is disabled because it expects builtin objects to have
attributes (__lt__, __gt__, etc.).
Another test for compatibility with pickle is also disabled because
pickle compatibility is currently broken.
Bumped package version to 0.0.8.
The functools code in CPython has the following credits:
