2c884b8bd2 feat(tvix/nix-compat): enable more features by default
There's no point in not enabling these, and rust-analyzer is quite
useless too.

nix-compat users outside of here can still explicitly disable default
features if they don't want to pull in these features.

cf47294b9e feat(tvix/boot): boot nixos VM
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.

28e98af9bc fix(tvix/castore/blobservice/chunk_rd): only skip *first* chunk bytes
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.

8fed8982b7 feat(nix/buildkite): reflect deps between derivations in pipelines
Most of the steps in our buildkite pipeline build derivations without
doing anything else. A lot of those derivations depend on each other.
Consequently, buildkite will schedule builds of derivations whose
dependencies are still in the process of being built. The result is many
buildkite agents doing nothing but blocking on other derivations being
built. We can easily prevent this by using the dependency information we
can get from the derivation (files) of the targets we want to build and
translating them into buildkite step dependencies.

The hard part of this has already been done for a while:
//nix/dependency-analyzer finds the dependencies between a list of
“known” derivations (even if they only depend on each other through
intermediate derivations) without depending on a specific derivation
builder convention, but rather relying on `.drv` files. It still has a
few rough edges, but has been working reliably for our purposes.

Since our steps are identified by derivation hashes, we can just
directly use the available dependency data. Luckily, buildkite seems to
just takes a step as if it was completed if it is skipped, so we don't
even have to check whether dependencies have been skipped or not.

On whitby it seems that the dependency analysis costs about a minute
additionally (which is how long it takes to run
//nix/dependency-analyzer in isolation just about).

Supersedes cl/5063, cl/5060, cl/5064 and cl/5065.

dce1a7480c feat(nix/buildkite): use keys based on drvPaths where possible
This will make it easier to emit intra pipeline dependencies based on
the dependencies between derivations contained therein later.

A consequence of this change is that it is no longer possible to have
the same derivation be exposed as multiple steps in the pipeline. I
doubt that having this is very useful, though.

Keys for extraSteps are not changed significantly, but are distinguished
from derivation based steps (with prefix `drv-*`) by their prefix
`extra-step-*`.

b025a30d27 refactor(tvix/castore/fs): remove From<Node> for InodeData
These were copying unnecessarily. Instead, have a
InodeData::from_node(), which *consumes* the Node entirely, returns
`InodeData` and the split-off name (which is not part of InodeData).

Callers can then use the result in various helper functions, like:

 - InodeData::as_fuse_type
 - InodeData::as_fuse_file_attr
 - InodeData::as_fuse_entry

… to prepare their replies to the kernel.

This removes not only a bunch of clones, but also a lot of copy-pasted
code.

9498ac936e fix(tvix/castore/directory): fix graph traversal
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.

34d9d54aae fix(tvix/castore/fs): use record to add fields to current span
Instead of creating another child span, we can use
`tracing::Span::current().record(k,v)` to add an additional field to the
current span.

ff5835008f feat(tvix/castore/fs): implement readdirplus
This currently shares some code with readdir, except it's also providing
a second `fuse_backend_rs::api::filesystem::Entry` argument to the
`add_entry` function call.

Refactoring this to reduce some duplication is left for a future CL.

456191e69e refactor(tvix/castore/fs): use consistent span field name for handle
Use rq.handle in `release` too, and remove interpolating it into the
log message itself.

Also update the comment, we don't get ownership, just simply drop, and
change the level to warn!, as suggested in cl/11425.

2a47ad1d90 feat(tvix/castore/fs): implement opendir/releasedir
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.

515bfa18fb feat(tvix/castore/fs): support extended attributes
This exposes `user.tvix.castore.{blob,directory}.digest` xattr keys for
files and directories:

```
❯ getfattr -d /tmp/tvix/06jrrv6wwp0nc1m7fr5bgdw012rfzfx2-nano-7.2-info
getfattr: Removing leading '/' from absolute path names
user.tvix.castore.directory.digest="b3:SuYDcUM9RpWcnA40tYB1BtYpR0xw72v3ymhKDQbBfe4="

❯ getfattr -d /tmp/tvix/156a89x10c3kaby9rgf3fi4k0p6r9wl1-etc-shells
getfattr: Removing leading '/' from absolute path names
user.tvix.castore.blob.digest="b3:pZkwZoHN+/VQ8wkaX0wYVXZ0tV/HhtKlSqiaWDK7uRs="
```

It's currently mostly used for debugging, though it might be useful for
tvix-castore-aware syncing programs using the filesystem too.

01f8ef1560 fix(tvix): apply cbtemulator patch in tvix view
This tells josh to include the patch from
third_party/overlays/patches/cbtemulator-uds.patch at
nixpkgs/cbtemulator-uds.patch.

We then use the `additionalOverlays` feature introduced earlier, and
pass it an overlay adding the patch to `cbtemulator`.

This only gets applied if tvix/shell.nix is not called with a pkgs
argument, which is the case in the tvix view.

especially considering this is in the same crate [1], it doesn't hurt to
add that annotation too.

Suggested in cl/11385.
