0f74816d43 feat(users/Profpatsch/netencode.rs): parse multiple stdin values
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.

A kingdom for a conduit.

d44203d046 fix(third_party/overlays/dhall): move haskellPackages overlay
It was overriding the overrides in haskellPackages, which we didn’t
notice because there is no overrides in the hasell overlay atm.

I also removed the `with` blocks and inlined `overrides`.

f816813d41 feat(tvix/eval): implement 'builtins.filter'
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.

1015f2f8e7 fix(tvix/eval): manually count entries in recursive scopes
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.

Fixes b/199

64d3efcc2c fix(tvix/eval): handle thunks in arithmetic builtins
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).

c46025d520 fix(tvix/eval): support string identifiers in inherits
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).

7bf1b4deea refactor(tvix/eval): drop empty Word version cmp rule
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.

083fc1dbe5 fix(tvix/eval): compare versions with an extra empty component
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`.

9a8a6a33f9 fix(tvix/eval): implement C++ Nix version part comparison algorithm
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.

0096939bf6 feat(tvix/eval): implement builtins.splitVersion
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.

28417afbb4 fix(nixery): Avoid race when the same image is fetched in parallel
Remove a race condition which appears when uploadHashLayer is called
with the same key from multiple threads simultaneously. This can
easily happen when the same image path is requested by multiple
clients at the same time. When it does, a 500 status is returned and
the following error message is logged:

{
  "context": {
    "filePath": "github.com/google/nixery/builder/builder.go",
    "lineNumber": 440,
    "functionName": "github.com/google/nixery/builder.uploadHashLayer"
  },
  "error": "rename /var/lib/nixery/staging/<hash> /var/lib/nixery/layers/<hash>: no such file or directory",
  "eventTime": "...",
  "layer": "<hash>",
  "message": "failed to move layer from staging",
  ...
}

To solve this issue, introduce a mutex keyed on the uploaded hash and
move all layer caching into uploadHashLayer. This could additionally
provide a small performance benefit when an already built image is
requested and NIXERY_PKGS_PATH is set, since symlink layers and config
layers are now also cached.

ae98240df2 feat(gerrit): add code-owners plugin
This is the New Thing that is intended to replace the find-owners
and owners plugins.

In particular:

* It inserts a submit requirement rather than providing a Prolog
  predicate.
* The default OWNERS file formats are suspiciously Googley.
* It provides a neat UI for finding OWNERS and tracking approval
  state on a per-file basis.

When we fully migrate to using the code-owners plugin, a few
things will need to land, which I will likely do "offline"
directly to the Gerrit backing Git repos:

* Add the corresponding Gerrit config
* Replace OWNERS files depot-wide
* Add OWNERS files to the refs/meta/config branch
* Introduce the Owners-Override label, settable by depot-interventions

The enclosed patch adds two extra pieces of functionality that
we need in tvldepot but aren't upstream:

1. The ability to just specify usernames rather than email addresses
2. The ability to specify `group:GROUPNAME`, _as long as_ that group is
   visible to everyone. This is a restriction intended to avoid having
   the plugin just leak group membership.

b79e248959 refactor(tvix/eval): handle forcing in Builtin::apply
Instead of arity, we pass a array reference to Builtin::new that
describes how many arguments there are and which of them need to be
forced, eliminating the need to force manually.

Note that this change doesn't fix some of the instances where the the
Builtin doesn't consider that the value could be a Thunk.

fefa8c55c4 feat(tvix/eval): Support builtins.tail
TL;DR:
- support `builtins.tail`
- define `ErrorKind::TailEmptyList` and canonical error code
- support basic unit tests

Unsure whether or not the error should be a dedicated `ErrorKind`...
