`ingest_entries` requires that all directories referenced by entries in
the ingestion stream have an explicit entry in the stream.
For example, if the stream contains a file with path `foo/bar`, there
must be an entry that comes later in the stream for the directory `foo`.

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.

Use a proper graph library to ensure all nodes are reachable from the
root.
We had a bit of that handrolled during add(), as well as later, which
had an annoying bug:
Redundant nodes were omitted during insert, but when returning the list
during finalize, we did not properly account they need to be introduced
before their parents are sent.
We now simply populate a petgraph DiGraph during insert (skipping
inserting nodes we already saw), and use petgraph's DfsPostOrder to
traverse the graph during finalize.
If the number of returned indices equals the total number of nodes in
the graph, all nodes are reachable from the root, we can consume the
graph and return the nodes as a vec, in the same order as the traversal
(and insertion).
Providing a regression test for the initial bug is challenging, as the
current code uses a bunch of HashSets. I manually tested ingesting a
full NixOS closure using this mechanism (via gRPC, which exposes this
problem, as it validates twice), and it now works.

This can be used to validate a Directory closure (connected DAG of
Directories), and their insertion order.
Directories need to be inserted (via `add`), in an order from the leaves
to the root. During insertion, we validate as much as we can at that
time:
- individual validation of Directory messages
- validation of insertion order (no upload of not-yet-known Directories)
- validation of size fields of referred Directories
Internally it keeps all received Directories (and their sizes) in a HashMap,
keyed by digest.
Once all Directories have been inserted, a drain() function can be
called to get a (deduplicated and) validated list of directories, in
from-leaves-to-root order (to be stored somewhere).
While assembling that list, a check for graph connectivity is performed
too, to ensure there's no separate components being sent (and only one
root).
It adds a test suite for these cases, which is much nicer to test than
where we previously had these checks (only in the gRPC server wrapper).
Followup CLs will move the existing putters to use this.

Use this to control the set of feature flags for the object_store

In the future this can be used to enable/disable other cloud backends

Without feature flags, `object_store` already supports the `InMemory`

This currently is still a bit stupid, and doesn't compose, as
`ChunkedReader` uses `self` as the `BlobService` to ask for the
individual chunks.
In store composition future, we might want to compose this differently,
essentially constructing `ChunkedReader` with another `BlobService`
representing the entire hierarchy, so there's a chance to locally cache
things, and do less requests.

`build.rs` emits rerun-if-changed statements for all proto files, as
well as all include paths we pass it.
Unfortunately, due to protobufs include path rules, we need to specify
the path to the depot root itself as an include path, at least when
building impurely with `cargo`. This causes cargo to essentially always
rebuild, as it also puts its own temporary files in there.
Unfortunately, tonic-build does not chase down to individual .proto
files that are included.
Disable emitting these `rerun-if-changed` statements for now.
This could cause cargo to not rebuild protos every time, causing stale
data until the next local `cargo clean`, but considering the protos
change not that frequently, and it'll immediately surface if trying to
build via Nix (either locally or in CI), it's a good-enough compromise.

To make use of the filtering feature, we need to revert the internal walker to a real DFS.
We will therefore just invert the whole tree by storing all of its
contents in a level-keyed vector.
This is horribly expensive in memory, this is a compromise between CPU
and memory, here is the fundamental reason for why:
When you encounter a directory, it's either a leaf or not, i.e. it
contains subdirectories or not.
To know this fact, you can:
- wait until you notice subdirectories under it, i.e. you need to store
any intermediate nodes you see in the meantime -> memory penalty.
- getdents or readdir on it to determine *NOW* its subdirectories -> CPU
penalty and I/O penalty.
This is an implementation of the first proposal, we pay memory.
In practice, we are paying O(#nb of nodes) in memory.
There's a smarter albeit much more complicated algorithm that pays only
O(\sum_i #siblings(p_i)) nodes where (p_1, ..., p_n) is the path to a leaf.
which means for:
A
/ \
B C
/ / \
D E F
We would never store D, E, F but only E, F at a given time.
But we would still store B, C no matter what.

While theoretically all chunk-awareness could be kept private inside
each BlobService reader, we'd not be able to resolve individual chunks
from different Blobservices - and due to this, not able to substitute
chunks we already have in a more local store.
This function allows asking a BlobService for the list of chunks,
leaving any actual fetching up to the caller (be it through individual
calls to open_read), or asking another store for it.

We can also drop the Clone requirement. Because the trait is async since
some time, there's no need to clone before moving into an async closure,
allowing us to simplify the code a bit.

There's no need to pass in an unused directory service into the
populate_blob_* method, and considering we have one or two invocation of
each of these, we don't really gain much from having all these functions
follow the same structure, at least for now.
Also, update some function names to better describe what they're doing.

cl/10378 did already move store/fs to castore/fs, but we kept the tests
in tvix-store, as they were populating a PathInfoService to make nodes
appear in the mount root.
Update these tests to now just insert root nodes into a BTreeMap, and
ensure we can use that as a RootNodes too.

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.
