Introduce [`t-rec`](https://github.com/sassman/t-rec-rs), a terminal
recorder.
Usage:
```bash
nix run .#t-rec
```
Upon exit, `t-rec` will save recordings of the session to disk in GIF
and MP4.

NOTE: even though the latest upstream version is 2.1.46 we cannot use
this as every rustracer version technically requires nightly Rust. We
work around this by setting `RUSTC_BOOTSTRAP`, but also have to stick to
older versions where each used "nightly" feature is already in a `rustc`
that's also available in `nixpkgs`.

Hydra build: https://hydra.nixos.org/build/142609369
One instance of this error/warning comes up during the build.
According to the comment in the code they know what they are doing,
so this can be ignored.

We split configuration-hackage2nix.yaml into multiple files. We bump
cabal2nix-unstable to get support for multiple config files in
hackage2nix.
* The file main.yaml is only supposed to be edited by humans.
* The file stackage.yaml is only supposed to be updated by the
update-stackage.sh
* The file broken.yaml can be edited by humans, but probably future
helpers will want to insert broken packages into this file based on
hydra reports.
* The file transitive-broken.yaml is newly introduced to be generated
by regenerate-transitive-broken-packages.sh
regenerate-transitive-broken-packages.sh makes a nix query (in
transitive-broken-packages.nix) which evaluates all haskellPackages
once with and once without "allowBroken" this way it get's a list of
packages which are broken by some transitive dependency, but does not
disable packages which have eval errors not caused by a broken package.
