With the recent introduction of the RootNodes trait, there's nothing in
the fs module pulling in tvix-store dependencies, so it can live in
tvix-castore.
This allows other crates to make use of TvixStoreFS, without having to
pull in tvix-store.
For example, a tvix-build using a fuse mountpoint at /nix/store doesn't
need a PathInfoService to hold the root nodes that should be present,
but just a list.
tvix-store now has a pathinfoservice/fs module, which contains the
necessary glue logic to implement the RootNodes trait for a
PathInfoService.
To satisfy Rust orphan rules for trait implementations, we had to add a
small wrapper struct. It's mostly hidden away by the make_fs helper
function returning a TvixStoreFs.
It can't be entirely private, as its still leaking into the concrete
type of TvixStoreFS.
tvix-store still has `fuse` and `virtiofs` features, but they now simply
enable these features in the `tvix-castore` crate they depend on.
The tests for the fuse functionality stay in tvix-store for now, as
they populate the root nodes through a PathInfoService.
Once above mentioned "list of root nodes" implementation exists, we
might want to shuffle this around one more time.
Fixes b/341.

To support tvix builds, we need to be able to use the `TvixStoreFs` to
materialize the sandbox's /nix/store filesystem with just the list of
inputs needed for the build. Currently we'd need to seed an in-memory
`PathInfoService`, which includes more functionality than what is
required for `TvixStoreFs`. Additionally, the `PathInfoService` is
specific to Nix. By decoupling `TvixStoreFs` and `PathInfoService`,
we allow for usage of `TvixStoreFs` with `tvix-castore` without needing
a `PathInfoService`.
This introduces a new `RootNodes` trait which provides a way for the
filesystem to look up CA nodes via their basename in the root directory
of the filesystem. We then implement `RootNodes` for any
`PathInfoService`. Additionally, the filesystem root inode tracker now
stores basenames rather than `StorePath`s since `StorePath`s are
specific to Nix.
As a followup we can rename `TvixStoreFs` to `TvixCaStoreFs` and move
it to the `castore` crate (or its own crate).

It's been a while since the last sled release, and that one binds to a
pretty old version of zstd, requiring workarounds like cl/10090.
Upstream sled main branch currently has zstd halfway patched out (it's
a no-op, but the feature flag and options are still there), and it's in
that state for a year.
Rather than maintaining our own fork of sled, let's just stop using the
compression feature in sled, dropping the version pin to zstd that way,
removing the need for cl/10090.
This doesn't mean we won't reintroduce per-blob compression - but we
probably just won't let sled take care of the compression, but do it
ourselves - which is necessary for more chunked blob storage anyways.
Even though we do drop the feature flag, we still need to explicitly use

NixHTTPPathInfoService acts as a bridge in between the Nix HTTP Binary
cache protocol provided by Nix binary caches such as cache.nixos.org,
and the Tvix Store Model.
It implements the [PathInfoService] trait in an interesting way: Every
[PathInfoService::get] fetches the .narinfo and referred NAR file,
inserting components into a [BlobService] and [DirectoryService], then
returning a [PathInfo] struct with the root.
Due to this being quite a costly operation, clients are expected to
layer this service with store composition, so they're only ingested
once.
The client is expected to be (indirectly) using the same [BlobService]
and [DirectoryService], so able to fetch referred Directories and Blobs.
[PathInfoService::put] and [PathInfoService::nar] are not implemented
and return an error if called.
This behaves very similar to the nar-bridge-pathinfo code in nar-bridge,
except it's now in Rust.

We don't gain much from making this part of the trait, it's still up to
`tvix_store::pathinfoservice::from_addr` to do most of the construction.
Move it out of the trait and into the specific *Service impls directly.

Unfortunately, it's not compatible with tonic right out of the box so I

This is not a simple get and put returning digest.
You currently can get by output hash, and a put gives you back the
(possibly modified) PathInfo message.

We've decided to asyncify all of the services to reduce some of the
pains going back and for between sync<->async. The end goal will be for
all the tvix-store internals to be async and then expose a sync
interface for things like tvix eval io.

In prepration for adding virtiofs support, I thought it would make sense
to split out the filesystem implementation from FUSE itself.
The `fs` module holds the tvix-store filesystem implemetation and the
`fuse` module holds the code to spawn a FUSE daemon backed by multiple
threads.

This switches the FUSE implementation from fuser to fuse-backend-rs.
fuse-backend-rs is designed to work with both FUSE and virtiofs.
Virtiofs support will make it possible to plug the tvix-store into a
microvm and have `/nix/store` access without having to setup FUSE inside
the guest.
Additionally fuse-backend-rs has nice support for running multiple FUSE
threads and has some async support.
The goal of this commit is to mechanically switch over to
fuse-backend-rs with minimal changes. I did have to add some locks here
and there because fuse-backend-rs uses `&self` on all methods whereas
fuser uses `&mut self`. `&self` is required for concurrent access to the
FUSE server, so this makes sense.
We can consider switching to concurrent maps and use some other
techniques to reduce lock contention and critical section size.

This wasn't removed yet, and no code is using/populating it so far.
It's confusing, let's update it to the state of things now, and re-
introduce it once we get there.

We were blindly returning 0o444 for all regular files, but regular files
with executable bit need to be 0o555.
This wasn't spotted because stat'ing executable files was not part of
the test suite, it's now added.

We previously kept the trait of a BlobService sync.
This however had some annoying consequences:
- It became more and more complicated to track when we're in a context
with an async runtime in the context or not, producing bugs like
https://b.tvl.fyi/issues/304
- The sync trait shielded away async clients from async worloads,
requiring manual block_on code inside the gRPC client code, and
spawn_blocking calls in consumers of the trait, even if they were
async (like the gRPC server)
- We had to write our own custom glue code (SyncReadIntoAsyncRead)
to convert a sync io::Read into a tokio::io::AsyncRead, which already
existed in tokio internally, but upstream ia hesitant to expose.
This now makes the BlobService trait async (via the async_trait macro,
like we already do in various gRPC parts), and replaces the sync readers
and writers with their async counterparts.
Tests interacting with a BlobService now need to have an async runtime
available, the easiest way for this is to mark the test functions
with the tokio::test macro, allowing us to directly .await in the test
function.
In places where we don't have an async runtime available from context
(like tvix-cli), we can pass one down explicitly.
Now that we don't provide a sync interface anymore, the (sync) FUSE
library now holds a pointer to a tokio runtime handle, and needs to at
least have 2 threads available when talking to a blob service (which is
why some of the tests now use the multi_thread flavor).
The FUSE tests got a bit more verbose, as we couldn't use the
setup_and_mount function accepting a callback anymore. We can hopefully
move some of the test fixture setup to rstest in the future to make this
less repetitive.

WrongSorting(Vec<u8>) actually encodes the name of a node, so if we can,
we want this to display it as a string (and fall back to the base64
encoding if we can't).
