hardware: use march=native for generic module.

test: fix tests with a shallow clone.

java_requirement.rb: use HTTPS in Java Platform URL

Fix “Hombrew” typo.

Fix `uninstall :pkgutil` leaving empty `.app` directories.

It's redirected to cleartext, though this URL will be opened
in a browser so it won't be something hidden, and maybe
Oracle will fix this in the future.

`ENV.prepend_path "PATH", which("emacs").dirname` in the emacs
requirement was causing us to end up invoking /usr/bin/clang instead
of /usr/local/Homebrew/Library/Homebrew/shims/super/clang.

This matches Linux where this behaviour was original imported from.

Refactor artifacts.

Python requirements: Remove casks

linux: Add ARM to CPU.type

Neither python nor python3 are available from Caskroom.

super/cc: Fix --cc=llvm_clang invoked as clang

In this case `HOMEBREW_VERSION` is `>1.1.0 (no git repository)` so these
tests failed. This was the cause of the Homebrew/homebrew-test-bot
Linux CI failures as it was testing a shallow clone.

Fix the error:
brew sh --cc=llvm_clang <<<'clang --version'
Failed to execute llvm_clang --version

Refactor `pkg`, `uninstall`, and `zap` artifacts.

Move `brew cask --version` into separate file.

Always `chmod +x` `binary` stanzas.

style: improve Rubocop error handling.

keg: resolve rack aliases correctly.

audit: do not warn about reachability of `brew mirror`ed URL

- Check if the JSON is definitely invalid (< 2 characters)
- Output the arguments that were passed to Rubocop

Don't use the basename but instead use the Formulary logic for rack
formula resolution.

Fixes #2288.

Use `ArgumentError` instead of `CaskError` in `CLI`.

Refactor CLI options.

Remove redundant `Utils`.

Move legacy cache and caskroom code to `compat/*`.
