These are all packages that I stopped using and hence just create noise
in my inbox for each change affecting them and let's face it, while I
still enjoy contributing to nixpkgs, it doesn't really make sense to be
listed there if I can't do much anyways.
Each of these packages can be taken over by someone or removed if
people think that's reasonable.
Of course, if other maintainers face issues, I can answer some questions
if needed & possible.
Rust 1.50.0 incorporated a Cargo change (rust-lang/cargo#8937) in
which cargo vendor erroneously changed permissions of vendored
crates. This was fixed in Rust
1.51.0 (rust-lang/cargo#9131). Unfortunately, this means that all
cargoSha256/cargoHashes produced during the Rust 1.50.0 cycle are
potentially broken.
This change updates cargoSha256/cargoHash tree-wide.
Fixes#121994.
