As part of the unification of binding logic between different carriers
of bindings, we need to track which kind of bindings we are dealing
with (attribute set? recursive scope? ...) to correctly emit keys and
declare identifiers in the locals stack.
Right now this changes no functionality as `BindingsKind::Attrs` is
not yet used (only RecAttrs and LetIn, which was previously
represented by the `rec_attrs` boolean).

This helper will gain the ability to compile both kinds of inherits,
but it is kind of tricky to get right so I am doing it in smaller
steps. Right now there is no change in functionality.

Changes the module structure of the compiler to have a module
dedicated to the logic of setting up bindings. This logic is in the
process of being merged between attribute sets and `let`-expressions,
and the structure of the modules makes more sense when ecapsulating
that specifically.
(Other bits of code related to e.g. attribute sets are pretty
straightforward and can just live in the main compiler module).

Adds support for parsing multiple netencode values from stdin.
This is overly complicated for my tastes, but I don’t see a better way
of writing this logic that does not read all of stdin before starting
to parse the first value.

This is a little ugly because the plain Iterator::filter method can
not be used (it does not support fallible primitives), so we need to
resort to an `Iterator::filter_map` and deal with the wrapping in
Options everywhere.
This prevents use of `?` which introduces the need for some matching,
but it's not *too* bad.

The previous version had a bug where we assumed that the number of
entries in an attribute set AST node would be equivalent to the number
of entries in the runtime attribute set, but due to inherit nodes
containing a variable number of entries, this did not work out.

The simplest solution seems to be to pass references to arithmetic_op!()
which avoids the moving annoyance we had to deal with in the
builtins (no more popping!). We then use .force() to force the values
and dereference any Thunks (which arithmetic_op! doesn't do for us).

This updates rnix-parser to a version where inherits provide an
iterator over `ast::Attr` instead of `ast::Ident`, which mirrors the
behaviour of Nix (inherits can have (statically known) strings as
their identifiers).
This actually required some fairly significant code reshuffling in the
compiler, as there was an implicit assumption in many places that we
would have an `ast::Ident` node available when dealing with variable
access (which is then explicitly only not true in this case).

This was derived from
else if (c1 == "" && n2) return true; // true implies c1 < n2
However, this has no effect since Word always looses out against Number
anyways and the `pre` rules are also unaffected by this change – since
this only affects comparison of an empty Word part with a Number.

This is necessary because builtins.compareVersions compares versions in
a subtly not-quite-but-still-lexicographical way: `pre` for example can
have an effect if it is post-fixed: `2.3 < 2.3pre`. This is a violation
of the rule that in a lexicographical ordering, the longer string is
considered greater if they are otherwise equal. builtins.compareVersion
is comparing lexicographically though, if you do the following
transformation beforehand:
2.3 --split--> [ "2" "3" ] --append--> [ "2" "3" "" ]
2.3pre --split--> [ "2" "3" "pre" ] --append--> [ "2" "3" "pre" "" ]
Comparing the transformed version is then done lexicographically:
2.3 < 2.3.0pre since [ "2" "3" "" ] < [ "2" "3" "0" "pre" ]
Here, the `pre` rule never comes into effect because no comparison on it
happens, instead we use the longer string rule of a lexicographical
comparison.
In the C++ codebase, the reason for this behavior is that the
iterator-esque construct they use always yields the empty string before
it exposes it has been fully consumed. This is probably intentional to
support the postfixed `pre` which is, for example, used by NixOS
versions (e.g. unstable post 22.05 is 22.11-pre). We replicate this
behavior using the `Chain` iterator in `VersionPartsIter::new_for_cmp`.

This is based on the [relevant code] in C++ Nix. Our version has more
branches because the C++ one only checks if it is less than or not, so
can save handling a few cases. We on the other hand, can avoid calling
the algorithm twice. It'd be nice to implement proptests for this in the
future and to make sure that this weird little algorithm doesn't violate
the Ord laws.

This was fairly easy, thanks to the work already done by Thomas Frank.
However, the implementation is suboptimal because we parse number parts
only to convert them back to strings afterwards. I've chosen to tackle
this problem in the future, since having an (inefficient) implementation
of splitVersion will be helpful for debugging the slight discrepancies
between C++ Nix and Tvix in the case of compareVersions.

This makes it possible to call a callable value (builtin or

for pretty much all higher-order functions to work correctly.
This is mostly equivalent to the previous code in coerce_to_string for
calling `__toString`, except it expects the argument(s) to already be
placed on the stack.
Note that the span for the `NotCallable` error is not currently
guaranteed to make any sense, will experiment with this.
