Remove potential partial reads/writes and instead read/write the full
buffer size: we want those to be 64 bits.

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.

Write counterpart of read_bytes. Despite its name, we mostly use it to
write strings (as in ascii strings) to the wire.
We also extract the padding calculation in its own function.

This is currently unused, and even if it would be used, it'd probably
be with `default-features = false`, explicitly enabling what's needed.

Implementing the full connection handshake.
The integration test is a bit naive, but there's not much to test yet.
Tested this against cpp nix. We reach the stage where cppnix sends the
opcode.

Adding a VM integration test setup for tvix-daemon. This test acts as
our first milestone: implementing enough daemon operations to be able
to add a new store path to tvix-store.
The test is expected to fail for now. We don't want to run it on CI
yet.

This daemon is a re-implementation of the Nix daemon except it uses
tvix-store as a remote store.
For now, it's very barebones, this is just a quick and dirty setup to
get started with the project. We bind to the unix socket provided by
systemd, wait for cpp Nix to send the magic hello bytes, respond with
the magic hello bytes and call it a day.
Storing this under my username for now, the project is mostly
irrelevant as it is. We'll move it to Tvix if it gets complete and
relevant at some point.
