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.

This adds `bind`, `listen`, and `accept` implementations based on
`wasi-sockets` for the `wasm32-wasip2` target.

* implement basic TCP/UDP client support
This implements `socket`, `connect`, `recv`, `send`, etc. in terms of
`wasi-sockets` for the `wasm32-wasip2` target.
I've introduced a new public header file: `__wasi_snapshot.h`, which will define
a preprocessor symbol `__wasilibc_use_wasip2` if using the `wasm32-wasip2`
version of the header, in which case we provide features only available for that
target.

Since the socket address of the accepted socket is unknown,
all bytes are set to zero and the length is truncated to the size
of the generic `struct sockaddr`.

See the WHATSNEW file for details. The biggest change in musl is the
switch to 64-bit time_t for 32-bit targets, however WASI libc was already
using 64-bit time_t. The main change affecting WASI is an update to
Unicode 12.1.0.
Most of the changes are in threads, TLS, dynamic linking, and other
features wasi doesn't yet use, but there are some bug fixes in code
wasi does use.
atanl.c - local changes no longer needed as they've now landed upstream.
include/alltypes.h.in - Upstream now makes FILE a complete type in
pre-C11 mode. For WASI, this level of pre-C11 strictness isn't as
important, and having multiple incompatible definitions of _IO_FILE
that are kept separate only by clever use of translation unit
boundaries can confuse some tools, so stick with the incomplete type.
Add at least a one-line comment on every
`#ifdef __wasilibc_unmodified_upstream` briefly indicating what its
purpose is.
While here, reenable some of the code that was previously disabled when
getenv wasn't supported, as getenv is now supported.
