This also includes stubs for `gethostbyname`, `gethostbyaddr`, etc. which were
necessary to get CPython to build. I believe it will be possible to implement
them all properly at some point, but don't have the bandwidth at the moment.
Finally, this includes a few fixes for issues I missed in earlier PRs that
surfaced when running the CPython `asyncio` test suite.
