rust-1.67.1

[ken@…]

Since we have decided to use 1.67.0, presumably we need to upgrade again.

What's in 1.67.1 stable

Rust 1.67.1 fixes a regression for projects that link to thin archives (.a files that reference external .o objects). The new archive writer in 1.67.0 could not read thin archives as inputs, leading to the error "Unsupported archive identifier." The compiler now uses LLVM's archive writer again, until that format is supported in the new code.

Additionally, the clippy style lint uninlined_format_args is temporarily downgraded to pedantic -- allowed by default. While the compiler has supported this format since Rust 1.58, rust-analyzer does not support it yet, so it's not necessarily good to use that style everywhere possible.

The final change is a soundness fix in Rust's own bootstrap code. This had no known problematic uses, but it did raise an error when bootstrap was compiled with 1.67 itself, rather than the prior 1.66 release as usual.
