3a4e29c261 refactor(tvix/store): rename import::{import_path -> ingest_path}
This distinguishes it better from the EvalIO::import_path method.
Also update the docstring to explain what it does (and what it doesn't).

616fa4476f refactor(tvix/store): remove ChunkService
Whether chunking is involved or not, is an implementation detail of each
Blobstore. Consumers of a whole blob shouldn't need to worry about that.
It currently is not visible in the gRPC interface either. It
shouldn't bleed into everything.

Let the BlobService trait provide `open_read` and `open_write` methods,
which return handles providing io::Read or io::Write, and leave the
details up to the implementation.

This means, our custom BlobReader module can go away, and all the
chunking bits in there, too.

In the future, we might still want to add more chunking-aware syncing,
but as a syncing strategy some stores can expose, not as a fundamental
protocol component.

This currently needs "SyncReadIntoAsyncRead", taken and vendored in from
https://github.com/tokio-rs/tokio/pull/5669.
It provides a AsyncRead for a sync Read, which is necessary to connect
our (sync) BlobReader interface to a GRPC server implementation.

As an alternative, we could also make the BlobReader itself async, and
let consumers of the trait (EvalIO) deal with the async-ness, but this
is less of a change for now.

In terms of vendoring, I initially tried to move our tokio crate to
these commits, but ended up in version incompatibilities, so let's
vendor it in for now.

26c68f8e89 refactor(nix-compat): Properly encapsulate store path construction
Before there was code scattered about (e.g. text hashing module and
derivation output computation) constructing store paths from low level
building blocks --- there was some duplication and it was easy to make
nonsense store paths.

Now, we have roughly the same "safe-ish" ways of constructing them as
C++ Nix, and only those are exposed:

- Make text hashed content-addressed store paths

- Make other content-addressed store paths

- Make input-addressed fixed output hashes

5f2c2e79e1 refactor(tvix/nix-compat): move build_store_path out of derivation
This doesn't have anything to do with ATerms, we just happen to be using
the aterm representation of a Derivation as contents.

Moving this into store_path/utils.rs makes these things much cleaner -
Have a build_store_path_from_references function, and a
build_store_path_from_fingerprint helper function that makes use of it.

build_store_path_from_references is invoked from the derivation module
which can be used to calculate the derivation path.

In the derivation module, we also invoke
build_store_path_from_fingerprint during the output path calculation.

2fe53cce40 feat(tvix/store/directorysvc): add DirectoryService::get_recursive()
This moves the recursive BFS traversal of Directory closures from the
GRPCDirectoryServiceWrapper out into a a DirectoryTraverser struct
implementing Iterator.

It is then used from various implementors of DirectoryService in the
`get_recursive()` method.

This allows distinguishing between recursive requests and non-recursive
requests in the gRPC client trait implementation.

367a5e9922 feat(tvix/store/directorysvc): add gRPC client
This provides a GRPCDirectoryService struct implementing
DirectoryService, allowing a client to Directory objects from a (remote)
tvix-store.

Remote in this case is anything outside the current process, be it
another process, or an endpoint on the network.

To keep the sync interface in the `DirectoryService` trait, a handle to
some tokio runtime needs to be passed into the constructor, and the two
methods use `self.tokio_handle.spawn` to start an async function, and
`self.tokio_handle.block_on` to wait for its completion.

The client handle, called `grpc_client` itself is easy to clone, and
treats concurrent requests internally. This means, even though we keep
the `DirectoryService` trait sync, there's nothing preventing it from
being used concurrently, let's say from multiple threads.

There's still two limitations for now:

1) The trait doesn't make use of the `recursive` request, which
   currently leads to a N+1 query problem. This can be fixed
   by `GRPCDirectoryService` having a reference to another
   `DirectoryService` acting as the local side.
   I want to wait for general store composition code to pop up before
   manually coding this here.

2) It's currently only possible to put() leaf directory nodes, as the
   request normally requires uploading a whole closure. We might want
   to add another batch function to upload a whole closure, and/or do
   this batching in certain cases. This still needs some more thinking.

We can also use `read_all_and_chunk`, it's just requires a bit more
plumbing:

 - The data coming from the client (stream) needs to be mapped (we

 - The stream needs to be turned into an (async) reader
 - The reader needs to be made sync, and that code using the sync reader
   needs to be in a `task::spawn_blocking`.

510927e43a feat(tvix/store): use rayon to upload chunks concurrently
Look at the data that's written to us, and upload all chunks but the
rest in parallel, using rayon. This required moving `upload_chunk`
outside the struct, and accepting a ChunkService to use for upload
(which it was previously getting from `self.chunk_service`).

This doesn't speed up things too much for now, because things are still
mostly linear.

a40d2dcdcd feat(tvix/store): bump fastcdc, use v2020 version
This switches away from the less canonical "ronomon" version to the
implementation as described in the
[paper](https://ieeexplore.ieee.org/document/9055082) by Wen Xia, et
al., in 2020.

That version uses 64-bit hash values and tends to be faster than both
the ronomon and v2016 versions, and produces the same chunking as the
2016 version.

As per https://docs.rs/fastcdc/latest/fastcdc/#implementations-1, it's
the recommended choice.

The crate also gained support for streaming version of chunkers:
https://docs.rs/fastcdc/latest/fastcdc/#large-data, which might be
useful.

0db73cb2bd feat(tvix/store): add write_nar function
This adds a function that consumes a [proto::node::Node] pointing to the
root of a (store) path, and writes the contents in NAR serialization to
the passed [std::io::Write].

We need this in various places:

 - tvix-store's calculate_nar() RPC method needs to render a NAR stream
   to get the nar hash, which is necessary to give things imported in
   the store a "NAR-based" store path.

 - communication with (remote) Nix (via daemon protocol) needs a NAR
   representation.

 - Things like nar-bridge, exposing a NAR/NARInfo HTTP interface need a
   NAR representation.

5ba47a2bc3 feat(tvix/store): parameterise validate_node_name error
We'll be using validate_node_name in other places in a bit, where
returning a ValidateDirectoryError is not appropriate.

Accept a function mapping a string to error as a second argument, and
pass ValidateDirectoryError::InvalidName at the current call sites.

The only warnings left are unused warnings, but that'll change once we
have a real implementation, and not just tests.

lazy_static is only used in tests, and anyhow isn't used at all (yet).

This can be dropped.

Move them from the bottom of src/proto.rs to its own src/tests/mod.rs.
