To maintain backwards compatibility, this can't be changed in the Nix language.
We can however ensure that the version Nixpkgs has the more intuitive behavior.
This license is used by the Fraunhofer FDK codec, which is currently
mislicensed to Apache 2.0.
Of course, this can't be corrected without having the proper license
available in lib.licenses can't it??
Thanks @trofi for noticing this has an SPDX ID.
The v2 dashboard (included since version 1.41.0) is licensed under
Netdata Cloud UI License v1.0, which is a non-free license.
Patch the source code so that the v2 is not included in the source
and the result derivation. Users that want the v2 dashboard can still
request it by overriding this derivation and pass `withCloudUi = true`.

Mean CPU time 0.04006 (σ = 0.0040146) for 10 runs is 8.193619775953792% (σ = 0.9584251052704821%) of the old value 0.488917 (σ = 0.0294955)

We can now test returned paths being equal, no need to work around it
anymore by making sure paths aren't returned (which would import them
with the previous --json)
The Minimalist Gnu for Windows distribution comes with support for
the traditional msvcrt libc, as well as ucrt64 libc. The latter
being the newer universal compiler runtime. We follow the msys2
environment naming convention[1]:
| name | toolchain | arch | libc | libc++ |
|------------|-----------|---------|--------|-----------|
| mingw32 | gcc | i686 | msvcrt | libstdc++ |
| mingw64 | gcc | x86_64 | msvcrt | libstdc++ |
| ucrt64 | gcc | x86_64 | ucrt | libstdc++ |
| clang32 | llvm | i686 | ucrt | libc++ |
| clang64 | llvm | x86_64 | ucrt | libc++ |
| clangarm64 | llvm | aarch64 | ucrt | libc++ |
For now nixpkgs only supports the first three with this commit.

What it does: line and column level *declaration* position information:
$ nix repl .
nix-repl> :p nixosConfigurations.micro.options.environment.systemPackages.declarationPositions
[ { column = 7; file = "/nix/store/24aj3k7fgqv3ly7qkbf98qvphasrw9nb-source/nixos/modules/config/system-path.nix"; line = 63; } ]
Use cases:
- ctags over NixOS options, as will be presented at NixCon 2023 ;)
- improving the documentation pages to go to the exact line of the
declarations.
Related work:

This one does it for all *definitions* rather than declarations, and
it was not followed through with due to performance worries.

The basis for this change. This change is just a rebase of that one.
I split it out to add the capability before adding users of it, in
order to simplify review. However, the ctags script in there is a
sample user of this feature.
Benchmarks: conducted by evaluating my own reasonably complex NixOS
configuration with the command:
`hyperfine -S none -w 1 -- "nix eval .#nixosConfigurations.snowflake.config.system.build.toplevel.outPath"`
```
Benchmark 1: nix eval .#nixosConfigurations.snowflake.config.system.build.toplevel.outPath
Time (mean ± σ): 8.971 s ± 0.254 s [User: 5.872 s, System: 1.388 s]
Range (min … max): 8.574 s … 9.327 s 10 runs
Benchmark 1: nix eval .#nixosConfigurations.snowflake.config.system.build.toplevel.outPath
Time (mean ± σ): 8.766 s ± 0.160 s [User: 5.873 s, System: 1.346 s]
Range (min … max): 8.496 s … 9.033 s 10 runs
```
Summary of results: it seems to be in the noise, this does not cause any
visible regression in times.
