continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
Since version `0.6.0` the `rust-src` component (or declaring
`RUST_SRC_PATH`) is needed. Just like in `rust-analyzer`, this is solved by
setting `RUST_SRC_PATH` to `rustPlatform.rustLibSrc` for tests and
wrapped executables.
ChangeLog: https://github.com/google/evcxr/blob/v0.6.0/RELEASE_NOTES.md#version-060
Changes the default fetcher in the Rust Platform to be the newer
`fetchCargoTarball`, and changes every application using the current default to
instead opt out.
This commit does not change any hashes or cause any rebuilds. Once integrated,
we will start deleting the opt-outs and recomputing hashes.
See #79975 for details.
The `cargoSha256` hashes across the sourcetree had to be altered after
the last `cargo-vendor` bump. Also ensured that `cc` is available in
`$PATH` to avoid startup errors in the REPL.
