a35dadf9f0 refactor(tvix/derivation): use BTreeSet for derivation outputs
When constructing derivations inside builtins.derivationStrict, we'd
have to very frequently check whether certain outputs have already
been inserted into the derivation inputs.

Using a set type is much easier, especially as this has to be ordered
and the source data that is being inserted also comes from a set,
which might let us pass this more efficiently in the future.

Note that the validate function no longer checks the order of the
entries, as that is now guaranteed by the type.

3045645df0 feat(tvix/cli): implement initial refscan module
This module implements a ReferenceScanner struct which uses the
aho_corasick crate to scan string inputs for known, non-overlapping
candidates (store paths, in our case).

I experimented with several different APIs, and landed on this version
with an initial accumulator in the scanner. The scanner is
instantiated from the candidates and "fed" all the strings, then
consumed by the caller to retrieve the result.

Right now only things that look vaguely like bytestrings can be fed to
the scanner, there is no streaming support in the API yet.

cb764e87de refactor(users/edef/refscan): switch to intrinsics
packed_simd is deprecated, but we don't need very much SIMD:
  * _mm256_set1_epi8 / vpbroadcastb (splat)
  * _mm256_cmpgt_epi8 / vpcmpgtb (comparison)
  * _mm256_movemask_epi8 / vpmovmskb (compress to bitmask)

This also simplifies the code by only vectorising the bare minimum,
since we just get a bitmask and operate in scalar mode as soon as
possible.

We don't need nightly Rust anymore: we're using only stable intrinsics.

cd40585ea4 feat(users/Profpatsch/netencode): Add initial Haskell parser
A simple categorical parser that does not implement Monad, and does
not contain an `m` and some rudementary error message handling.

In the future I’d probably want to wrap everything in an additional
`m`, so that subparsers can somehow use `Selective` to throw errors
from within `m` that contain the parsing context if at all possible.
Hard to do without Monad, I have to say. Not even stuff like `StateT`
works without the inner `m` implementing `Monad`.

396fdde0c0 refactor(tvix/derivation): use StorePath::to_absolute_path()
Instead of concatenating STORE_DIR manually, use
StorePath::to_absolute_path() that does it for us.

1ebda9e13e fix(tvix/derivation): fix build after StorePath rename
This project was not previously covered by CI (fixed in this commit),
so we didn't catch breakage due to a renamed module.

This was noticed while rebasing a CL that has a dependency on this
crate in its Nix build.

3e03e59893 refactor(tvix/store): move protobuf build config one level up
This embeds the build config directly at the point where `Cargo.nix`
is imported, making it transparent to library consumers.

999afd4be2 test(tvix/derivation): add output_path_construction test
This exercises the output path calculation functions like a constructing
client (an implementation of builtins.derivation) would do.
It first assembles the bar derivation, does the output path calculation
on it, then continues with the foo derivation.

The code ensures the resulting Derivations match our fixtures.

9df9a2f1ab feat(tvix/derivation): add get_fixed_output() helper function
This will return the fixed output of a derivation (and its hash), or
None if the Derivation is not fixed-output.

It will simplify the logic in the output path calculation a bit.
