Improves https://github.com/apple/containerization/pull/245. A potential
deadlock risk was not proven. This PR moves the closing operation inside
the lock to prevent leaking an unclosed handle in case of an error.
While individual accesses were properly mutex-protected, the logical
operations were not atomic, leading to a potential inconsistency in a
multi-threaded environment. Multiple separate `state.withLock` calls
created race windows. With the proposed changes, single atomic
operations check and update the state together.
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.
