When a directory or file is open()'ed, we already put some data into
a lookup table, and subsequent operations then use the returned handle
id.
By also adding the span that's been created during these calls into the
lookup table, we can properly set the span parent for these requests,
nicely connecting the individual operations to the bigger picture.

Similar to how we already handle opening files, implement opendir/
releasedir, and keep a map of dir_handles. They point to the rx side of
a channel.
This greatly improves performance listing the root of the filesystem
when used inside tvix-store, as we don't need to re-request the listing
(and skip to the desired position) all the time.

This drops pretty much all of castore/utils.rs.
There were only two things left in there, both a bit messy and only used
for tests:
Some `gen_*_service()` helper functions. These can be expressed by
`from_addr("memory://")`.
The other thing was some plumbing code to test the gRPC layer, by
exposing a in-memory implementation via gRPC, and then connecting to
that channel via a gRPC client again.
Previous CLs moved the connection setup code to
{directory,blob}service::tests::utils, close to where we exercise them,
the new rstest-based tests.
The tests interacting directly on the gRPC types are removed, all
scenarios that were in there show now be covered through the rstest ones
on the trait level.

This creates test scenarios (using the DirectoryService trait) that we
want all DirectoryService implementations to pass.
Some of these tests are ported from proto::tests::grpc_directoryservice,
which tested this on the gRPC interface (rather than the trait),
some others ensure certain behaviour for which we only recently
introduced general checking logic (through ClosureValidator).
We also borrow some code related to setting up a gRPC DirectoryService
client (connecting to a server exposing a in-memory DiretoryService)
from castore::utils, this will be deleted once it's all ported over.

This greatly simplifies the code in this function, replacing it with a
much better tested (and more capable!) version of the validation logic.
It also enables the gRPC server frontend to make use of the
DirectoryPutter interface. While this might not be too visible in terms
of latency thanks to gRPC streams bursting, it also enables further
optimizations later (such as bucketing of directory closures).

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.

This controls whether tvix-castore has support for various cloud

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
too.
Without feature flags, `object_store` already supports the `InMemory`
and `LocalFilesystem` backends, and we also want to unconditionally
enable the `http` one. Make sure at least the construction of these
services is covered in the tests.
Similarly, the tvix-store crate, which provides the tvix-store CLI has a

Whenever this encounters an open_read(), it'll first check for more
granular chunking. If there's more granular chunking data available, a
ChunkedReader is constructed (which supports seeking backwards).
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.
