This allows calling validate() on a derivation that doesn't have its
output paths already calculated yet. It allows offloading some of the
error checking in builtins.derivation* to be offloaded to that function.

This uses the exposed StorePath::validate_name method to check for other

`drv` is an invalid output name too, as this would cause a
`builtins.derivation` call to return an attrset with a `drvPath` key
(which already exists) and has a different meaning.
Also handle errors during store path construction, and return our own
error type, instead of the ParseStorePathError.

Instead of having a representation of suspended native thunks that
involves constructing a fake code chunk, make these thunks a
first-class part of the internal thunk representation.
The previous code was not that simple to understand, and actually
contained a critical bug which could lead to Tvix crashes. This
version fixes the particular instance of that bug, but instead
uncovers another (b/238) which can still lead to Tvix crashes.
Fixes: b/237.

This is a somewhat terrifying hack that enables us to support
`builtins.builtins`, by running a "fake compilation" inside of a
suspended native thunk that can resolve the weak pointer to the
globals.
With this implementation, the thunk at `builtins.builtins` actually
resolves to the "real" `builtins` (verified with a new test).
This is kind of ugly, and it's something users shouldn't use, but
bubbling a warning out of this is difficult at the moment due to a
little bit of trickery with how the spans in suspended native thunks
work (they don't) (see b/237, b/238)

Replacement strings are some weird internal feature of Nix that is
required for calculating derivation hashes. We need to track these
like other paths, as they need to be re-used on builds with
dependencies on values from previous builds.

When adding things to a C++ Nix store, ensure that the path is tracked
in the tracker.
Since the mechanism for propagating the tracker instance isn't
finalised yet, I've opted to take an Rc<RefCell> parameter for it. How
exactly that ends up there is going to become clear in the next
commits, but for now it's just instantiated in main with
Default::default.

Instead of going through Vec/BTreeMap for generating our internal
types, use the proptest strategies from imbl.
The one thing I couldn't figure out in the previous implementation is
where the ranges/sizes of generated collections came from. The
strategies in proptest use different types (Range, with an unknown
default value, and SizeRange with 0..100). I've opted to specify
0..100 directly, but we can probably make it configurable.

Different to the go-nix implementation, we don't have a custom "writing
mode" where output paths are omitted from output, but we simply run the
serialization with these fields unpopulated (during construction).
This means, there's no need for a custom writing mode that strips
outputs, so we can drop the comments.

This variant is required for external builtins (which in our case
includes `derivation`) to thread through reasonable error messages.
This has some potential for improvement, but it's an improvement over
the status quo of panicking in the external builtins when no
appropriate error is available.

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.

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.
