Refactor the `strict` boolean passed into evaluation at the top-level to
be a (two-variant, so far) EvalMode enum of Lazy and Strict.
This is more explicit than a boolean, and if we ever add more EvalModes
it's a simple extension of the enum.

Make constructing of a new Evaluation use the builder pattern rather
than setting public mutable fields. This is currently a pure
refactor (no functionality has changed) but has a few advantages:
- We've encapsulated the internals of the fields in Evaluation, meaning
we can change them without too much breakage of clients
- We have type safety that prevents us from ever changing the fields of
an Evaluation after it's built (which matters more in a world where we
reuse Evaluations).
More importantly, this paves the road for doing different things with
the construction of an Evaluation - notably, sharing certain things like
the GlobalsMap across subsequent evaluations in eg the REPL.

This one's relatively simple - we just check if the store path exists,
and if it does we make a new contextful string containing the store path
as its only context element.
Automatic testing seems tricky for this (I think?) so I tested it
manually:
tvix-repl> builtins.storePath /nix/store/yn46i4xx5alh7gs6fpkxk430i34rp2q9-hello-2.12.1
=> "/nix/store/yn46i4xx5alh7gs6fpkxk430i34rp2q9-hello-2.12.1" :: string

XmlEmitter gains a NixContext field, and `write_typed_value` extends it
with all context elements present in the passed value.
Once all serialization is done, a into_context() function returns the
collected context, so we can construct a NixString with context.
Tests for this live in tvix-glue, as we use builtins.derivation, which
is not present in the tvix-eval crate.
Fixes b/398.

This shouldn't be part of the PathInfoService trait.
Pretty much none of the PathInfoServices do implement it, and requiring
them to implement it means they also cannot make use of this calculation
already being done by other PathInfoServices.
Move it out into its own NarCalculationService trait, defined somewhere
at tvix_store::nar, and have everyone who wants to trigger nar
calculation use nar_calculation_service directly, which now is an
additional field in TvixStoreIO for example.
It being moved outside the PathInfoService trait doesn't prohibit
specific implementations to implement it (like the GRPC client for the
`PathInfoService` does.
This is currently wired together in a bit of a hacky fashion - as of
now, everything uses the naive implementation that traverses blob and
directoryservice, rather than composing it properly. I want to leave
that up to a later CL, dealing with other parts of store composition
too.

Nix supports file:// - URLs for `fetchurl` and `fetchTarball`.
Convert the enums and function arguments to hold a URL type.
reqwest::Url is a re-export of the url crate, but they don't re-export
the parsing errors, and as we want to hold these in our Error types, add
it to Cargo.toml explicitly.
The Fetcher::download function now checks on the scheme, and either
opens the file locally, or does do a HTTP request as before.
Fetch gets its custom debug impl, removing potentially sensitive
username and password out of URLs.

`toJSON` transform a Nix structure into a JSON string.
For each context in that Nix structure, the JSON string must possess it.
Thus, it is necessary to take the union of all contexts and attach it to
the final structure.
Unfortunately, the return type of `into_json` is a serde's JSON object,
not a string. Therefore, it is not possible to reuse `NixString`
machinery.
Context tests are reinforced as Nix does not test those behaviors.
Fixes b/393.

`appendContext s ctx` will just append a user-crafted context attrs to `s`.
The most important part of this builtin is to perform all the relevant invariant validations
to avoid letting the user craft invalid contexts which can never be built, e.g. invalid store paths,
inexistent derivations, etc.
This version is incomplete and full of TODOs, but passes all the Nix's
context strings tests, so we turn them on.

stream to determine which compression format is being used out of the
three that are supported by builtins.fetchTarball, and switches to the
correct decompression algorithm adapter dynamically.

We add a new set of builtins called `import_builtins`, which
will contain import-related builtins, such as `builtins.path` and
`builtins.filterSource`. Both can import paths into the store, with
various knobs to alter the result, e.g. filtering, renaming, expected
hashes.
We introduce `filtered_ingest` which will drive the filtered ingestion
via the Nix function via the generator machinery, and then we register
the root node to the path info service inside the store.
`builtins.filterSource` is very simple, `builtins.path` is a more
complicated model requiring the same logic albeit more sophisticated
with name customization, file ingestion method and expected SHA-256.

These builtins are added to the evaluation context using a similar

This is an additional test suite on the top of the Nix ones
for context strings matters.
It already smoked out multiple mistakes and potential bugs and non-deterministic result from the evaluator.
It uses a similar technology as the one in the tvix-eval albeit we instantiate a fully fledged evaluator

We copy the files instead of symlinking them because crates are built in
isolation, so symlinks cannot work.
