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.

Previously, we were assembling very naively an attribute set composed of context we saw.
But it was forgetting that `"${drv}${drv.drvPath}"` would contain 2 contexts with the same key, but
with different values, one with `outputs = [ "out" ];` and `allOutputs = true;`.
Following this reasoning and comparing with what Nix does, we ought to merge underlying values systematically.
Hence, I bring `itertools` to perform a group by on the key and merge everything on the fly, it's not
beautiful but it's the best I could find, notice that I don't use
`group_by` but I talk about group by, that is, because `group_by` is a
`group_by_consecutive`, see
https://github.com/rust-itertools/itertools/issues/374.
Initially, I tried to do it without a `into_grouping_map_by`, it was akin to assemble the final `NixAttrs` directly,
it was less readable and harder to pull out because we don't have a lot of in-place mutable functions on
our data structures.

This adds support to handle the __structuredAttrs argument, which can be
passed to builtins.derivationStrict.
If __structuredAttrs is passed, and set to true, most of the arguments
passed to builtins.derivationStrict are not simply coerced to a string
and passed down to "environments", but instead kept in a more structured
fashion.
Inside ATerm, which is what's relevant as far as path calculation is
concerned, a virtual `__json` environment variable is present,
containing these structured values.
Inside Builds, these structured values are not made available as an
environment variable, but a JSON file (and source-able bash script).
This will need to be respected once we start emitting BuildRequests,
and for that we can probably just parse the `__json` key in
Derivation.environment again - or keep this additionally in
non-serialized form around during Evaluation.
No matter what, this is left for a followup CL.
The existing handle_derivation_parameters and populate_outputs helper
function were removed, as __structuredAttrs causes quite a change
in behaviour, and so handling both in the same place makes it more
readable.
There's some open questions w.r.t. string contexts for structured attrs
itself. A TODO is left for this, but at least path calculation for
individual structured attrs derivations are correct now.

Nix essentially accepts any number of padding characters, no matter if

all padding characters, and parse it with BASE64_NOPAD and the length
the algo uses.

r/7176 introduced an incorrect assumption was the benefit of the
nonrecursive coercion algorithm, namely that a coercion operation always
returns a non empty string. This allows to detect whether we are
coercing a list or not by checking if the intermediate result is empty
or not. Unfortunately, coercing null and false yields an empty string,
so we need to explicitly track whether we are coercing a list.
Updated the test case to hopefully catch similar bugs in the future. I'm
not a hundred percent certain I have not introduced a new edge case with
this, so it may be interesting to add a prop test case for this to
nix_oracle down the line. At least lists are the only nested data
structures that can be serialized as nested data structures, so the
problem is kind of limited.

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.

To support tvix builds, we need to be able to use the `TvixStoreFs` to
materialize the sandbox's /nix/store filesystem with just the list of
inputs needed for the build. Currently we'd need to seed an in-memory
`PathInfoService`, which includes more functionality than what is
required for `TvixStoreFs`. Additionally, the `PathInfoService` is
specific to Nix. By decoupling `TvixStoreFs` and `PathInfoService`,
we allow for usage of `TvixStoreFs` with `tvix-castore` without needing
a `PathInfoService`.
This introduces a new `RootNodes` trait which provides a way for the
filesystem to look up CA nodes via their basename in the root directory
of the filesystem. We then implement `RootNodes` for any
`PathInfoService`. Additionally, the filesystem root inode tracker now
stores basenames rather than `StorePath`s since `StorePath`s are
specific to Nix.
As a followup we can rename `TvixStoreFs` to `TvixCaStoreFs` and move
it to the `castore` crate (or its own crate).

The default behavior of string coercion in C++ Nix is to weakly coerce
and import to store if necessary. There is a flag to make it strongly
coerce (coerceMore) and a flag that controls whether path values have
the corresponding file/directory imported into the store before
returning the (store) path as a string (copyToStore). We need to
implement our equivalent to the copyToStore (import_paths) flag for the
benefit of weak coercions that don't import into the store (dirOf,
baseNameOf, readFile, ...) and strong coercions that don't import into
the store (toString).
This makes coerce_to_string as well as CoercionKind weirder and more
versatile, but prevents us from reimplementing parts of the coercion
logic constantly as can be seen in the case of baseNameOf.
Note that it is not possible to test this properly in //tvix/eval tests
due to the lack of an appropriate EvalIO implementation being available.
Tests should be added to //tvix/glue down the line.
