fd749070e2 refactor(tvix/nix-compat/wire): move magic bytes to worker_protocol
`primitive.rs` implements reading and writing primitive (fixed-length)
types in the wire format, used in the the nix daemon protocol and NAR
format.

Move worker-protocol specific magic bytes to worker_protocol.rs (and
possibly further split there once needed)

199f9b0a79 feat(tvix/nix-compat): read client setting from wire
Add the primitives necessary to read the client settings from the Nix
daemon wire protocol.

Introducing the read_string primitive. This trivial primitive parses a
read_bytes call, check the bytes are valid utf-8 bytes and wraps the
result in a String.

c35a5ff611 feat(users/picnoir/tvix-daemon): parse up to the operation
Using all the primitives recently implemented to nix-compat to reach
the point where the Nix client start to send us operation requests.

Using a small integration test script (or the VM test, but let's face
it, it's too slow to be useful), we manage to reach the point where
we're able to read a store operation:

    2024-03-21T18:53:27.624876Z  INFO tvix_daemon: Incoming connection addr=unix
    2024-03-21T18:53:27.625312Z  INFO worker:perform_init_handshake: tvix_daemon: Trust sent conn=Connection(unix) conn=Connection(unix)
    2024-03-21T18:53:27.625406Z  INFO worker: tvix_daemon: Client hanshake succeeded conn=Connection(unix)
    2024-03-21T18:53:27.625488Z  INFO worker: tvix_daemon: Operation received op=SetOptions conn=Connection(unix)

We had to take some shortcuts wrt. stderr/log management. The CPP Nix
codebase is a bit confusing in that area. I'll need to spend more time
reading this to fully understand what's happening there. For now,
sending the STDERR_LAST command to the client does the trick.

08cc27cc20 feat(tvix/nix-compat): introduce write_worker_trust_level
This is used by the nix client to determine whether or not the daemon
trust it. The trust conditions check are daemon-specific, hence not
part of nix-compat.
