cd40585ea4 feat(users/Profpatsch/netencode): Add initial Haskell parser
A simple categorical parser that does not implement Monad, and does
not contain an `m` and some rudementary error message handling.

In the future I’d probably want to wrap everything in an additional
`m`, so that subparsers can somehow use `Selective` to throw errors
from within `m` that contain the parsing context if at all possible.
Hard to do without Monad, I have to say. Not even stuff like `StateT`
works without the inner `m` implementing `Monad`.

5a063def51 chore(3p/sources): Bump channels & overlays
The main change is that nixpkgs updated to GHC 9.2 and Stackage LTS-20,
so we suffer from a bit of churn.

* //3p/overlays/haskell:

  - use updated dhall-nix patch for hnix 0.16

  - use superrecord fork with fixes for GHC 9.2

  - use graphmod-1.4.5.1 which has support for GHC 9.2

* //users/Profpatsch: relax constraints on base in Haskell pkgs

* //users/Profpatsch/cas-serve: inherit superrecord from 3p

* //users/grfn/xanthous:

  - //3p/overlays/haskell for 8.10.7:

    * Provide missing dependency of binary-orphans. Fix already commited
      upstream as e238c3fdaab710a2ce0135e5a77cd7e6bb023a22, can be
      dropped when channel advances.

    * Downgrade to brick 0.71.1, the latest version xanthous supports.

  - Adjust to generic-arbitrary >= 1.0, providing Arg constraints where
    necessary.

  - Increase constraint-solver-iterations to 6 (default 4), so
    Xanthous.Command and Xanthous.Data can be typechecked.

  - Drop NFData instances for Key and Modifier which have been added to
    vty upstream.

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.

ed68ba6751 feat(users/Profpatsch/netencode): ignore earlier record entries
It turns out that the netencode spec requiring to ignore *later*
entries meant that every parser has to do an extra check for each
element, instead of just overriding the key in the hash map.

This leads to a situation where the simple implementation is the wrong
one, which would lead to very subtle problems in parsers (see also the
infamous “json duplicate record entry” problem which has been used for
various exploits in the past).

To be fair, exploits are still possible, but at least a `Map.fromList`
will be the right implementation (provided it folds from the left) now
instead of the wrong one.

Examples of the trivial implementation being now right:

Python:

    > dict([("foo", 1), ("foo", 2)])
    {'foo': 2}

Rust:

    > println!("{:?}", HashMap::from([
      ("foo", 1),
      ("foo", 2)
    ]));
    {"foo": 2}

Haskell:

    > Data.Map.fromList [ ("foo", 1), ("foo", 2) ]
    fromList [("foo",2)]

0133fdc737 chore: move all 3p buildRustCrate derivations to //third_party
Profpatsch and me are basically the only users of
depot.users.Profpatsch.writers.rustSimple*. To pull in the odd
dependency we usually use buildRustCrate which is rather convenient.
However we've picked up the bad habit of inlining these in a let
somewhere instead of managing them in a more central location although
there has been an (unsuccesful) attempt at this in
//users/Profpatsch/rust-crates.nix.

This CL moves all buildRustCrate based derivations into
third_party.rust-crates and deletes any duplicate derivations we have
accumulated in the tree.

59a9955d75 feat(users/Profpatsch/netencode): fully streaming parser
In order to arbitrarily split netencode over multiple reads, we need
to make the parser completely streaming, so that it recognizes all
cases where it needs more input.

Luckily, this is fairly trivial, after working around a bunch of
overeager parsing.

The tricky part was the giant `alt`, where inner parsers would start
consuming input and thus become incomplete when they fail afterwards.
Sinc the format *always* starts the different types with one
discriminator char, we can use that to instantly return the parser and
try the next one instead.

The other tricky part was that lists and records would parse all inner
elements and then choke on the empty string after the last element,
because the inner parser would consume at least the descriminator, and
an empty string is always `Incomplete`. We wrap these into a small
combinator which plays nice with `many0` in that regard.

5d8490d2fc feat(users/Profpatsch): build attrset members on CI
Setting meta.targets to include all derivations in the different package
sets in Profpatsch's user folder makes them checked by CI until they do
the readTree refactor as promised.

To reduce code duplication we handle this in a simple function which is
exposed from nix.utils which may be a good place for depot specific bits
and bops we accumulate over time.

To get around the issue of too nested sets we perform the following
renames:

* users.Profpatsch.tests gets moved into its own directory
* users.Profpatsch.arglib.netencode now lives in its own file instead of
  the default.nix
* users.Profpatsch.netstring.tests gets moved into its own directory

3faf5b6f09 feat(users/Profpatsch/netencode): decode from U
Since we don’t necessarily need to decode deeply, we can make the
decoders take a `U` instead of a `T`.

e207785e1f feat(users/Profpatsch/{netencode,http-parse}): use HashMap
`U::Record` is required to be a hash map (later keys should be
ignored), so why not do the hash map immediately.

This surfaced a problem with read-http, because duplicate headers in
http are possible, but before they’d be silently ignored.
Now we merge them into a `U::List` in case, to be handled by
consumers of read-http.

42974ddd64 feat(users/Profpatsch/netencode): nest Us in U::List
Earlier we left the next level of values unencoded, since lists are
just concatenated netencode values. But I noticed that you can’t write
e.g. a `t_to_u` function, because only in the case of lists you need
to allocate memory.

Turns out that if we read the next level of values, everything is
handled the same as in `Record` and things suddenly start working.

We can also throw away some of the strange and ad-hoc parser helpers
we needed before, `skip` and `list_take`, since now those are just
normal `Vec::iter().skip()` and take.

Since `Text` is a scalar, it doesn’t make sense to delay the utf-8
verification to the consumer.

96edc545de fix(users/Profpatsch/netencode-rs-tests): reflect changed T::List type
a044a87084 removed boxes in T::List, but
the tests were not adjusted accordingly.

Seems like netencode fell victim to CI not recursing into attrsets not
generated by readTree in pipeline generation.

Seems like 5d44df3af6 forgot to add the
newly split out crate to the dependencies of netencode_mustache.

CI didn't pick up on it since it is hidden away from readTree in an
attrset in a file.

492b79ec7a feat(users/Profpatsch): add die_* helpers for semantic exit errors
There is this semantic exit code schema championed by execline and
skaware tooling, and we refined and documented it a bit in lorri
d1d673d420/src/ops/mod.rs (L24-L35)
in the past.

This just transcribes the error messages into simple helper functions.

Applies the functions to the places where we would panic or die
`sys::exit()` instead.

83634341aa feat(users/Profpatsch/execline): add args_for_exec
`exec_into_args` would just read argv and exec into it, but we want to
be able to write commands which take some positional arguments first.

Thus we split the invocation into `args_for_exec`, which returns the
positional arguments and prog, and then pass prog to `exec_into_args`
when we want to exec eventually (prog is still an iterator at this
point).

then the associated type is the actual return value of the decoder.

5d44df3af6 refactor(users/Profpatsch): move arglib_netencode into its own lib
arglib is the simple idea of passing structured data via a
conventional environment variable instead of implementing an optparser
for every little tool.

Pop the envvar, decode the contents, return the contents.
