`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.

Right now `builtins.hashFile` always reads the entire file into memory
before hashing, which is not ideal for large files. This replaces
`read_to_string` with `open_file` which allows calculating the hash of
the file without buffering it entirely into memory. Other callers can
continue to buffer into memory if they choose, but they still use the
`open_file` VM request and then call `read_to_string` or `read_to_end`
on the `std::io::Reader`.

`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.

It is pretty pointless to force the function argument if we are going to
use a suspended call later since forcing the function may fail in ways
that are not covered by Catchables (non-recoverable errors, infinite
recursions). From this, it kind of seems as if using #[catch] is never
correct and should be replaced by #[lazy]. Also we should probably try
to come up with more test cases for stuff where laziness gets us out of
the jam as an equivalent to the catchable tests for nonrecoverable
errors.

The primary addition is the `builtin_hashFile` function which attempts
value-path coercion and on success reads the file to a nix_string.
Similar to the `builtins_hashString` implementation, the hash is then
derived using the `hash_nix_string` function in the introduced hash
module which has extracted hashing functionality initially specified in
cl/11005.

Previously, Nix strings were represented as a Box (within Value)
pointing to a tuple of an optional context, and another Box pointing to
the actual string allocation itself. This is pretty inefficient, both in
terms of memory usage (we use 48 whole bytes for a None context!) and in
terms of the extra indirection required to get at the actual data. It
was necessary, however, because with native Rust DSTs if we had
something like `struct NixString(Option<NixContext>, BStr)` we could
only pass around *fat* pointers to that value (with the length in the
pointer) and that'd make Value need to be bigger (which is a waste of
both memory and cache space, since that memory would be unused for all
other Values).
Instead, this commit implements *manual* allocation of a packed string
representation, with the length *in the allocation* as a field past the
context. This requires a big old pile of unsafe Rust, but the payoff is
clear:

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

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

Tvix::Value represented by a Box<Path> rather than a Box<PathBuf> saves
us an indirection, while still avoiding the extra memory overhead of the
capacity which was the reason we were boxing PathBuf in the first place.

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.

Add a new --trace-runtime-timing flag (probably a better bikeshed for
this) that enables capturing the time, relative to the last event, of
each event recorded with the tracing observer.
This probably isn't *super* useful yet, but I'd like to start here in
adding new profiling tools to the VM, specifically based on the runtime
observer

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.
