Now that we can run this project on linux, lets add some unit tests for
the surfaces that don't..
This additionally changes delete to throw in most cases. I don't really
see how masking these errors is ideal.
This helps on binary size if we can successfully get all Foundation
imports out of our dep chain. It seems Foundation brings in a 30MiB ICU
blob, which bloats vmexec and vminitd.
Related to https://github.com/apple/containerization/issues/606
To make sure the project (and many linux specific libraries) builds on
linux lets add a linux step to build for both musl and glibc. Eventually
this will run unit tests as well. This change needs a bit more libc
agnostic-ifying work to make sure things work for both libcs.
This class does not work for glibc due to missing flags and methods.
This PR removes the ability to load the `Epoll` class when using glibc
for now.

- 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 change adds documentation to quite a few existing public types that
didn't have a blurb before.
Additionally, this fixes a couple things that I think either didn't make
sense when going to document them:
- Rename ConnectionStream to VsockConnectionStream. This type only
functions for vsock connections.
- Deletes NsLock+Closure. This was not used anywhere.
- Rename ContainerizationOCI/Config.swift to ImageConfig.swift.
