We actually want to delay fetching until we actually need the file. A
simple evaluation asking for `.outPath` or `.drvPath` should work even
in a pure offline environment.
Before this CL, the fetching logic was quite distributed between
tvix_store_io, and builtins/fetchers.rs.
Rather than having various functions and conversions between structs,
describe a Fetch as an enum type, with the fields describing the fetch.
Define a store_path() function on top of `Fetch` which can be used to
ask for the calculated store path (if the digest has been provided
upfront).
Have a `Fetcher` struct, and give it a `fetch_and_persist` function,
taking a `Fetch` as well as a desired name, and have it deal with all
the logic of persisting the PathInfos. It also returns a StorePathRef,
similar to the `.store_path()` method on a `Fetch` struct.
In a followup CL, we can extend KnownPaths to track fetches AND
derivations, and then use `Fetcher` when we need to do IO into that
store path.

Code reading through a non-seekable data stream has no choice but to

seekable (like a filesystem) probably knows better what concurrency to
pick when ingesting, rather than the consuming side.

Implement a first pass at the fetchTarball builtin.
This uses much of the same machinery as fetchUrl, but has the extra
complexity that tarballs have to be extracted and imported as store
paths (into the directory- and blob-services) before hashing. That's
reasonably involved due to the structure of those two services.
This is (unfortunately) not easy to test in an automated way, but I've
tested it manually for now and it seems to work:

Previously the store ingestion code was coupled to `walkdir::DirEntry`s
produced by the `walkdir` crate which made it impossible to reuse
ingesting from other sources like tarballs or NARs.
This introduces a `IngestionEntry` which carries enough information for
store ingestion and a future for computing the Blake3 digest of files.
This allows the producer to perform file uploads in a way that makes
sense for the source, ie. the filesystem upload could concurrently
upload multiple files at the same time, while the NAR ingestor will need
to ingest the entire blob before yielding the next blob in the stream.
In the future we can buffer small blobs and upload them concurrently,
but the full blob still needs to be read from the NAR before advancing.

This adds `Directory::add` which is a convenience helper for adding
nodes into a `Directory` while preserving sorted order.
This implements `Ord` and `PartialOrd` for `FileNode`, `SymlinkNode`,
and `DirectoryNode` so `binary_search` can be used.

This makes use of the vmCmdline and assertVMOutput to boot a NixOS VM
off of `tvix-store virtiofs` have it write a message on successful
bootup, then have it shut down again.
We check we see the message in the output.
Seeding the store with the closure it's what's currently taking most
of the time (as it's all linear still), so log a message before booting
the VM.

and can serve chunks from a local cache, we need to buffer the

When (re)initializing a chunked reader, we were erroneously skipping the
first n bytes from all chunks, not just the first one.
Fix this, by passing in an enumerated list of chunks, and only calling
SeekFrom::Start() on the first chunk in the stream.
With this, I'm able to invoke b3sum on bin/bash successfully.

Increase the discard_buf to 4096 (as I've seen this size).
Use the ready! macro to propagate pendings.
Make it more clear what exactly should be skipped in total, and what
during the current iteration.
Also write down that poll_read call already takes care of updating
self.pos, as I ran into that trap earlier (and added it here).
