The only user-facing change is handling non-integer (and zero) `RUST_THREADS` more nicely: ``` $ RUST_THREADS=x rustc # old You've met with a terrible fate, haven't you? fatal runtime error: runtime tls key not initialized Aborted $ RUST_THREADS=x ./x86_64-unknown-linux-gnu/stage2/bin/rustc # new You've met with a terrible fate, haven't you? fatal runtime error: `RUST_THREADS` is `x`, should be a positive integer Aborted ``` The other changes are converting some `for .. in range(x,y)` to `vec::from_fn` or `for .. in x.iter()` as appropriate; and removing a chain of (seemingly) unnecessary pointer casts. (Also, fixes a typo in `extra::test` from #8823.)

Improve "unknown field" error messages Fixes rust-lang#8806 Sample output: ``` error: error reading Clippy's configuration file `/home/smoelius/github/smoelius/rust-clippy/clippy.toml`: unknown field `foobar`, expected one of allow-expect-in-tests enable-raw-pointer-heuristic-for-send standard-macro-braces allow-unwrap-in-tests enforced-import-renames third-party allowed-scripts enum-variant-name-threshold too-large-for-stack array-size-threshold enum-variant-size-threshold too-many-arguments-threshold avoid-breaking-exported-api literal-representation-threshold too-many-lines-threshold await-holding-invalid-types max-fn-params-bools trivial-copy-size-limit blacklisted-names max-include-file-size type-complexity-threshold cargo-ignore-publish max-struct-bools unreadable-literal-lint-fractions cognitive-complexity-threshold max-suggested-slice-pattern-length upper-case-acronyms-aggressive cyclomatic-complexity-threshold max-trait-bounds vec-box-size-threshold disallowed-methods msrv verbose-bit-mask-threshold disallowed-types pass-by-value-size-limit warn-on-all-wildcard-imports doc-valid-idents single-char-binding-names-threshold at line 1 column 1 ``` You can test this by (say) adding `foobar = 42` to Clippy's root `clippy.toml` file, and running `cargo run --bin cargo-clippy`. Note that, to get the terminal width, this PR adds `termize` as a dependency to `cargo-clippy`. However, `termize` is also [how `rustc_errors` gets the terminal width](https://github.com/rust-lang/rust/blob/481db40311cdd241ae4d33f34f2f75732e44d8e8/compiler/rustc_errors/src/emitter.rs#L1607). So, hopefully, this is not a dealbreaker. r? `@xFrednet` changelog: Enhancements: the "unknown field" error messages for config files now wraps the field names.
