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.

WASI libc "bottom half".
The WASI libc "bottom half" is conceptually the lower half of a traditional libc implementation, consisting of C interfaces to the low-level WASI syscalls.
This implementation is partially derived from the "bottom half" of cloudlibc, revision 8835639f27fc42d32096d59d294a0bbb857dc368.
This implementation includes preopen functionality, which emulates POSIX APIs
accepting absolute paths by translating them into pre-opened directory handles
and relative paths that can be opened with openat. This technique is inspired
by libpreopen, however the implementation here is designed to be built into
libc rather than to be a layer on top of libc.
The WASI libc lower half currently depends on the dlmalloc component.
