From now on we will add the dependencies and their version in the root

we set `workspace = true` in the member's Cargo.toml.

This moves the URL component parsing code we had in nar-bridge to
nix-compat.
We change the function signature to return an Option, not a
Result<_, StatusCode>.
This allows returning more appropriate error codes, as we can
ok_or(…) at the callsite, which we now do: on an upload to an
invalid path, we now return "unauthorized", while on a GET/HEAD, we
return "not found".
This also adds support to parse compression suffixes. While not
supported in nar-bridge, other users of nix-compat might very well want
to parse these paths.
Also fix the error message when parsing NAR urls, it mentioned 32, not
52, which is a copypasta error from the narinfo URL parsing code.

This encodes a verified component on the type level. Internally, it
contains a bytes::Bytes.
The castore Path/PathBuf component() and file_name() methods now
return this type, the old ones returning bytes were renamed to
component_bytes() and component_file_name() respectively.
We can drop the directory_reject_invalid_name test - it's not possible
anymore to pass an invalid name to Directories::add.
Invalid names in the Directory proto are still being tested to be
rejected in the validate_invalid_names tests.

Nodes only have names if they're contained inside a Directory, or if
they're a root node and have something else possibly giving them a name
externally.
This removes all `name` fields in the three different Nodes, and instead
maintains it inside a BTreeMap inside the Directory.
It also removes the NamedNode trait (they don't have a get_name()), as
well as Node::rename(self, name), and all [Partial]Ord implementations
for Node (as they don't have names to use for sorting).
The `nodes()`, `directories()`, `files()` iterators inside a `Directory`
now return a tuple of Name and Node, as does the RootNodesProvider.
The different {Directory,File,Symlink}Node struct constructors got
simpler, and the {Directory,File}Node ones became infallible - as
there's no more possibility to represent invalid state.
The proto structs stayed the same - there's now from_name_and_node and
into_name_and_node to convert back and forth between the two `Node`
structs.
Some further cleanups:
The error types for Node validation were renamed. Everything related to
names is now in the DirectoryError (not yet happy about the naming)
There's some leftover cleanups to do:
- There should be a from_(sorted_)iter and into_iter in Directory, so
we can construct and deconstruct in one go.
That should also enable us to implement conversions from and to the
proto representation that moves, rather than clones.
- The BuildRequest and PathInfo structs are still proto-based, so we
still do a bunch of conversions back and forth there (and have some
ugly expect there). There's not much point for error handling here,
this will be moved to stricter types in a followup CL.

*Node and Directory are types of the tvix-castore model, not the tvix
DirectoryService model. A DirectoryService only happens to send
Directories.
Move types into individual files in a nodes/ subdirectory, as it's
gotten too cluttered in a single file, and (re-)export all types from
the crate root.
This has the effect that we now cannot poke at private fields directly
from other files inside `crate::directoryservice` (as it's not all in
the same file anymore), but that's a good thing, it now forces us to go
through the proper accessors.
For the same reasons, we currently also need to introduce the `rename`
functions on each *Node directly.
A followup is gonna move the names out of the individual enum kinds, so
we can better represent "unnamed nodes".

This uses our own data type to deal with Directories in the castore model.
It makes some undesired states unrepresentable, removing the need for conversions and checking in various places:
- In the protobuf, blake3 digests could have a wrong length, as proto doesn't know fixed-size fields. We now use `B3Digest`, which makes cloning cheaper, and removes the need to do size-checking everywhere.
- In the protobuf, we had three different lists for `files`, `symlinks` and `directories`. This was mostly a protobuf size optimization, but made interacting with them a bit awkward. This has now been replaced with a list of enums, and convenience iterators to get various nodes, and add new ones.

This ingests NAR files into the {Blob,Directory}Service, which are
already part of the AppState.
As we then need to correlate the root node to the uploaded PathInfo, we
need to keep a (short-lived) lookup table from NARHash to root node
around. We insert it into a `LruCache` after the NAR is uploaded, and
use `peek()` to do the lookup, which doesn't update the LRU list.

This adds an implementation of nar-bridge in Rust.
Currently, only the GET parts are implemented.
Contrary to the Go variant, this doesn't try to keep a mapping from nar
hashes to root node in memory, it simply encodes the root node itself
(stripped by its basename) into the URL.
This pulls in a more recent version of axum than what we use in
tonic, causing two versions of http and hyper, however dealing with
`Body::from_stream` in axum 0.6 is much more annoying, and
https://github.com/hyperium/tonic/pull/1740 suggests this will be fixed
soon.

Right now all blob uploads are performed synchronously, this means if a
NAR contains many small files, the import time is dominated by round
trip time to the blob service. For small files, we can buffer them in
memory and upload them asynchronously to the blob service. Before
returning we make sure to join all the uploads to make sure they
complete successfully before responding OK.
This reduces time to import a bash-interactive closure on my machine

We run narInfo.Check to ensure this parses to a StorePath, not
nixpath.Check.

This check makes more sense there, and gives stronger semantics - Done()
only succeeds if the other side successfully received everything, *and*
came up with the same hashes as we did.

This adds an additional nar-bridge-pathinfo command.
It exposes a PathInfoService for a HTTP Binary Cache, ingesting data
into a BlobService/DirectoryService as it goes through the NAR file.
It does this whenever it receives a Get request for a specific output
path, and waits returning with the PathInfo response until it ingested
the data.
It does not do any sort of caching - this means it re-downloads NAR
files again whenever the PathInfo is requested again, so you most likely
do not want to use this currently.
It's one building component as soon as we have store composition (which
we currently don't, so don't use this).
It can be used as an alternative mechanism to ingest data (Blobs and
Directories) of a given store path from a binary cache into tvix-store.
