Fix warnings introduced in newer Rust Nightly
This does not (yet) upgrade ./rust-toolchain The warnings: * dead_code "field is never read" * redundant_semicolons "unnecessary trailing semicolon" * non_fmt_panic "panic message is not a string literal, this is no longer accepted in Rust 2021" * unstable_name_collisions "a method with this name may be added to the standard library in the future" * legacy_derive_helpers "derive helper attribute is used before it is introduced" https://github.com/rust-lang/rust/issues/79202
