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.

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)

2024-03-21T18:53:27.625488Z 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.

This brings some initial Nix wire format parsing code, used in the nix
daemon protocol, remote store/builder protocol, as well as the NAR
format itself (note we already have more specialized code for the last
one).
Thanks to embr, this code already exists, in
https://codeberg.org/gorgon/gorgon/src/branch/main/nix-daemon/src/wire.rs,
and we can vendor it into here, as EUPL is compatible with GPL (in that
direction).
The code uses the tokio::io Reader and Writer traits, not the ones from
the `futures` crate, as they provide some more convenient `read_u64_le`
functions.
More application-specific parsing code, as well as code to read strings,
or bytes are left out for now, as we want to be be more restrictive
w.r.t allowed max sizes, and need to parse bytes, not strings.
The code slightly diverges, as we have clippy looped into CI.
`Ok(…?)` can be turned into just the inner expression, and
some .and_then can be expressed in a simpler fashion.

The outer fingerprint used for store path calculation is always a sha256
digest. This includes both input and output-addressed store paths.
We used a NixHash here, which can also represent other hash types, and
that had a bunch of annoyances:
- Whenever we had the bytes, we had to wrap them in a NixHash::Sha256().
- Things like AtermWriteable had to be implemented on NixHash,
even though we then had an assertion it was only called in the
NixHash::Sha256 case.

Implement the fetchurl builtin, and lay the groundwork for implementing
the fetchTarball builtin (which works very similarly, and is implemented
using almost the same code in C++ nix).
An overview of how this works:
1. First, we check if the store path that *would* result from the
download already exists in the store - if it does, we just return
that
2. If we need to download the URL, TvixStoreIO has an `http_client:
reqwest::Client` field now which we use to make the request
3. As we're downloading the blob, we hash the data incrementally into a
SHA256 hasher
4. We compare the hash against the expected hash (if any) and bail out
if it doesn't match
5. Finally, we put the blob in the store and return the store path
Since the logic is very similar, this commit also implements a *chunk*
of `fetchTarball` (though the actual implementation will likely include
a refactor to some of the code reuse here).
The main thing that's missing here is caching of downloaded blobs when
fetchurl is called without a hash - I've opened b/381 to track the TODO
there.
Adding the `SSL_CERT_FILE` here is necessary to teach reqwest how to
load it during tests - see 1c16dee20 (feat(tvix/store): use reqwests'
rustls-native-roots feature, 2024-03-03) for more info.

Currently CAHash only deserializes the hash in hex code while
the serializer outputs a nixbase32 hash. This means that you can't currently
deserialize what has been serialized.
This change makes deserialize support any digest format (so hex, nixbase32
and base64) as well as flattens the deserialize code and error handling.
It also implements serde methods of HashAlgo directly using Display and TryFrom
implementations because otherwise these would get serialized as eg. Sha256 instead
of sha256 which also broke CAHash serialize/deserialize.

We can simply use .to_owned() on that thing afterwards if we want to
construct an owned StorePath.

We always know this needs to end with a .drv, and fail parsing if it
doesn't, so there's no need to hang onto these 4 bytes.
This will make it much easier to synthesize a NarInfo<'_> later on from
a PathInfo proto, because we don't have to make this ".drv" appear out
of thin air.

These were used to format to and parse from strings.
Move this to the CAHash and NixHash structs directly, and be explicit in
the name about which encoding for digests is used.
For output path calculation, nix encodes the nixpaths in hex, but for
writing out NARInfos, it's using nixbase32.

Allow taking advantage of the buffer of the underlying reader to avoid
unnecessary copies of file data.
We can't easily implement the methods of BufRead directly, since we
have some extra I/O to perform in the final consume() invocation.
That could be resolved at the cost of additional bookkeeping, but this
will suffice for now.

We rely on being able to make small reads cheaply, so this was already
an implicit practical requirement. Requiring it explicitly removes a
performance footgun, and makes further optimisations possible.

This suggests it's cheap to convert around, but name actually does
allocate.
Move to a `to_owned(&self) -> StorePath`, to better signal that this
does allocate.
