*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 is the most naive version of string interning possible - we store a
map from the string itself to the pointer behind a global mutex, and
memoize the allocation of all strings below a threshold length (16
bytes, for now) into that map. This requires leaking /all/ strings,
since it's not easy to know just from the pointer that a string has been
interned - so interning is disabled if string leaking is also disabled.
In the case where we're leaking strings (the default), even the naive
version of this gets us a pretty nice perfomance boost:
hello outpath time: [742.54 ms 745.89 ms 749.14 ms]
change: [-2.8722% -2.0135% -1.0654%] (p = 0.00 < 0.05)
Performance has improved.
However, in the case where we're not leaking strings, we have to keep
track of which strings have and haven't been interned, which makes this
a little worse:
hello outpath time: [779.30 ms 792.82 ms 808.74 ms]
change: [+2.5258% +4.0884% +5.8931%] (p = 0.00 < 0.05)
Performance has regressed.
Hopefully we can close the gap here a bit with some clever
tricks (coming next).

Default to always leaking strings, and copying strings by copying
pointers rather than cloning the underlying allocation. This (somewhat
bafflingly) doesn't seem to affect any benchmarks, but paves the way for
some tricks around string allocation that do.
Unfortunately, we can't do this (yet?) for contextful strings, for
reasons I don't currently understand but which I will address later,
when I address contextful strings more holistically.
I've left a flag in here to disable this, both to test the cloning logic
for strings for when/if we decide to bring this back, and to allow
people who care more about memory usage than perf to disable leaking.

It introduces a new accept_trace function for axum0.7 which can be used
to accept a header trace from a received request. This function can be
used for tonic 0.12 once that version is released, and the specific
`accept_trace` function within `tvix_tracing::propagate::tonic` can then
be removed.
This also integrates http propagation into the nar_bridge crate.

This got broken while moving things around. We need to parse the

Since we're now validating the root node, we also need to rename the
root node to get past the node name validation.
There probably should be some tests for this.

In case two crate versions are present, the key in the Cargo.nix file

To be able to set a specific hash for "tracing-opentelemetry 0.25.0" for

We currently send 405, and that confuses `nix copy`.
Send a 404 for now, and add a futurework, as we can actually at least do
something more meaningful in case we still have that nar hash in our

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.
