The protocol is more stateful than I initially thought. We need to
keep track to a bunch of things, including but not limited to: the
client settings, the client version. I moved things around a bit to
keep this state along with the client socket.

This deals with writing byte packets of larger sizes to an underlying
AsyncWrite.
Its constructor receives the expected size. It also deals with writing
padding if flush/shutdown is called after writing all the payload.

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.

Update all 3p/sources as we do normally except
- agenix which is still pinned to 0.15.0
- nixpkgs (unstable) which we bump to the HEAD of the staging-next
branch. This branch includes the downgrade of xz from 5.6.1 to
5.4.6 (https://github.com/nixos/nixpkgs/commit/d6dc19adbd). It
also includes the second haskell-updates rotation with GHC 9.6.4
which contains a few build fixes that seem to be required to get
our Haskell targets to work.
Note that this only reverts xz to a version that doesn't contain the now
known backdoor (CVE-2024-3094) which may or may not actually affect
NixOS. Additionally reverting to a version before the malicious
contributor's involvement may be difficult, but prudent:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1068024
Changes required by the updates:
- //3p/overlays/haskell:
- Update ihp-hsx to latest master to fix build with Stackage LTS 22.
- Update tmp-postgres to latest master to work around failure with
ansi-wl-pprint >= 1.
- Patch punycode for mtl >= 2.3.
- //users/Profpatsch:
- Clean up some warnings, mostly about unused dependencies
- my-prelude: Fix build with ghc-boot-9.6.4
- cas-serve: Use crypton over unmaintained cryptonite
- ical-smolify: skip in ci, iCalendar would require heavy patching to
work with Stackage LTS 22.
- //users/{wpcarro,aspen,flokli}:
Disable home-manager / nixos configuration builds that seem to have
transient failures that should disappear as we move away from
staging-next and closer to an actual channel release.

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.
