We also use S in other places in the same file, but that's for the
string-like references.
SP is now consistently used as the type parameter for StorePath<_> (and
build_output_path) gets support for it).
By being a bit more careful in the order of assignments in nix-compat/
src/derivation, we can nudge the compiler to use the type we want.

Similar to how cl/12253 already did this for `Signature`, we apply the
same logic to `StorePath`.
`StorePathRef<'a>'` is now a `StorePath<&'a str>`, and there's less
redundant code for the two different implementation.
`.as_ref()` returns a `StorePathRef<'_>`, `.to_owned()` gives a
`StorePath<String>` (for now).
I briefly thought about only publicly exporting `StorePath<String>`
as `StorePath`, but the diff is not too large and this will make it
easier to gradually introduce more flexibility in which store paths to
accept.
Also, remove some silliness in `StorePath::from_absolute_path_full`,
which now doesn't allocate anymore.

We were wrongly using `'de` as a lifetime for both `Deserializer` and
`StorePathRef`.
This prevented Deserializing into a struct containing `StorePathRef`.
See https://serde.rs/lifetimes.html#the-deserializede-lifetime, the last
part of the paragraph:
The 'de lifetime should not appear in the type to which the Deserialize
impl applies.
- // Do not do this. Sooner or later you will be sad.
- impl<'de> Deserialize<'de> for Q<'de> {
+ // Do this instead.
+ impl<'de: 'a, 'a> Deserialize<'de> for Q<'a> {
This fixes it, and adds a test, deserializing into a `Container` struct.
It also fixes the existing test cases, deserialize_ref was actually
deserialize_owned, and deserialize_owned didn't exist yet - but they
alone are not enough to provoke the lifetime issues.

The outer fingerprint used for store path calculation is always a sha256
digest. This includes both input and output-addressed store paths.
We used a NixHash here, which can also represent other hash types, and
that had a bunch of annoyances:
- Whenever we had the bytes, we had to wrap them in a NixHash::Sha256().
- Things like AtermWriteable had to be implemented on NixHash,
even though we then had an assertion it was only called in the
NixHash::Sha256 case.

Implement the fetchurl builtin, and lay the groundwork for implementing
the fetchTarball builtin (which works very similarly, and is implemented
using almost the same code in C++ nix).
An overview of how this works:
1. First, we check if the store path that *would* result from the
download already exists in the store - if it does, we just return
that
2. If we need to download the URL, TvixStoreIO has an `http_client:
reqwest::Client` field now which we use to make the request
3. As we're downloading the blob, we hash the data incrementally into a
SHA256 hasher
4. We compare the hash against the expected hash (if any) and bail out
if it doesn't match
5. Finally, we put the blob in the store and return the store path
Since the logic is very similar, this commit also implements a *chunk*
of `fetchTarball` (though the actual implementation will likely include
a refactor to some of the code reuse here).
The main thing that's missing here is caching of downloaded blobs when
fetchurl is called without a hash - I've opened b/381 to track the TODO
there.
Adding the `SSL_CERT_FILE` here is necessary to teach reqwest how to
load it during tests - see 1c16dee20 (feat(tvix/store): use reqwests'
rustls-native-roots feature, 2024-03-03) for more info.
