Instead of constructing a completely new derivation for hashing,
allow to call hashing with substituted input_derivations.
This
1. reduces the number of allocations,
2. prepares substituting `String`s for store paths with proper `StorePath`s without needing a separate derivation struct that allows hashes without `/nix/store` in input_derivations, and
3. keeps the change local to the `Derivation` implementation.

Now that I've done a ton of things to make sure Value is small on the

This reverts commit d3d41552cf1f6485f8ebc597a2128a0d15b030a5.
This was well-intentioned, but now the boxed Path values are actually
the *largest* Value enum variants, at 16 bytes (because they're
fat-pointers, with a len) instead of 8 bytes like all the other values.
Having the double reference is a reasonable price to pay (it seems; more
benchmarks may end up disagreeing) for a smaller Value repr.

Storing a full BString here incurs the extra overhead of the capacity

In order to correctly propagate errors in the comparator passed to
builtins.sort, we need to do all the sorting in a context where we can
short-circuit return `Value`s (because catchables are Values on the `Ok`
side of the Result , not `Err`s). Unfortunately this means we have
to *inline* the List `sort_by` implementation into the builtin_sort
function - fortunately this is the only place that was called so this is
relatively low cost. This does that, and adds the requisite `try_value!`
invocation to allow us to propagate comparator errors here.
As before, this doesn't include tests, primarily since those are coming
in the next commit.

Rather than explicitly checking for Value::Catchable in all builtins,
make the #[builtin] proc macro insert this for all strict arguments by
default, with support for a #[catch] attribute on the argument to
disable this behavior. That attribute hasn't actually been *used*
anywhere here, primarily because the tests pass without it, even for
those builtins which weren't previously checking for Value::Catchable -
if some time passes without this being used I might get rid of support
for it entirely.
There's also a `try_value` macro in builtins directly for the places
where builtins were eg forcing something, then explicitly propagating a
catchable value.

directly in gRPC, as well as how clients should behave w.r.t. chunked
fetching was missing, or mixed together with the verified streaming

While there is no verified streaming version yet, a chunked one is
coming soon, and documenting this a bit better is gonna make it easier

C++ nix uses C-style zero-terminated char pointers to represent strings
internally - however, up to this point, tvix has used Rust `String` and
`str` for string values. Since those are required to be valid utf-8, we
haven't been able to properly represent all the string values that Nix
supports.
To fix that, this change converts the internal representation of the
NixString struct from `Box<str>` to `BString`, from the `bstr` crate -
this is a wrapper around a `Vec<u8>` with extra functions for treating
that byte vector as a "morally string-like" value, which is basically
exactly what we need.
Since this changes a pretty fundamental assumption about a pretty core
type, there are a *lot* of changes in a lot of places to make this work,
but I've tried to keep the general philosophy and intent of most of the
code in most places intact. Most notably, there's nothing that's been
done to make the derivation stuff in //tvix/glue work with non-utf8
strings everywhere, instead opting to just convert to String/str when
passing things into that - there *might* be something to be done there,
but I don't know what the rules should be and I don't want to figure
them out in this change.
To deal with OS-native paths in a way that also works in WASM for
tvixbolt, this also adds a dependency on the "os_str_bytes" crate.

In case a .exp.xml file is provided alongside the test, compare its
output with the desired state.
Also, add some function .exp.xml that were presumably moved out of the
way back to src/tests/nix_tests, as they now produce the correct XML
output.

These need to be preserved at least for builtins.toXML.
Also, we incorrectly only wrote an <attrspat> in case ellipsis was true,
but that's not the case.

At least toXML wants to get these out in a sorted fashion.

It's debateable on whether the serialization code should be exposed a
bit more prominently or not.

This relies on TEST_VAR=foo being set to "foo".
Nix does this in tests/functional/lang.sh, we do it in the test suite.

Right now all blob uploads are performed synchronously, this means if a
NAR contains many small files, the import time is dominated by round
trip time to the blob service. For small files, we can buffer them in
memory and upload them asynchronously to the blob service. Before
returning we make sure to join all the uploads to make sure they
complete successfully before responding OK.
This reduces time to import a bash-interactive closure on my machine
from 1m19s to 7s.
