* on glibc, swift expects that the msg_controllen is type Int

I didn't like how we expose the asyncstream via a public connections
field. We should have the type conform to AsyncSequence and then hide
the underlying stream. This also stops listening on the stdio ports
after we get the initial connection.
- Current implementation shuts down everything as soon as EOF is
detected on DispatchSourceRead for the relay. This is problematic for,
say an HTTP request where the client makes a request, and calls
`shutdown(fd, SHUT_WR)` to close the send side, but it expects to be
able to keep calling `recv()` to get the response.
- Changed cancel handlers so that the one that sees that both sources
have been cancelled then closes both the UDS and vsock fds.
- Updated vminitd VsockProxy to also do `shutdown(fd, SHUT_WR)` for read
hangup or EOF, and only close the underlying fds and unwire pollers on
full hangup, broken pipe, error, or when both sides half-close.
This is something I forgot to update ages ago. The field names, while
they do make sense, were different than the constructor names that
eventually set the fields themselves. This is kind of awkward, and I'd
much rather fix this now while it's much easier.
We'll need to update `container` after this
