- Tweak the way offline skipping happens
- Skip more tests that break when offline
- Hide more stdout output from tests.

We've been testing the recursive dependency check and allowing unlinked
dependencies in CI for a while with no adverse consequences so enable
them globally now for all users.

For many people `brew edit` makes use of the `EDITOR` variable to pick a
sensible editor. With environment filtering enabled unless this editor
is found in the default system PATH it'll fall back to e.g. `vim`.

Instead, ensure that we export the original, pre-filtering `PATH` as
`HOMEBREW_PATH` and use that internally to locate the editor. In future
this same approach will likely be used for requirements to be able to
find tools, too, and for other variables which we want to expose to
Homebrew itself but not other build tools.

Note that `HOMEBREW_PATH` is the same as `PATH` when build filtering
hasn't been enabled.

Option dependencies are nasty as they cause unnecessary builds from
source.

We may under some circumstances accept these anyway but it's better to
nudge people into the right behaviours on local `audit`s.

These formulae are detected as missing but exist in an unreadable form.

Fixes #2485

GitHub provides a description and homepage field so let `brew create`
use them where possible. Also, detect GitHub repositories based on
`releases` as well as `archive`s.

Add `--only` and `--except` methods which can be used to selectively
enable or disable audit groups.

This is useful for seeing when formulae are deleted if they are going to
leave behind any formulae that depend on them.

As a result, if there are any formulae returned return a non-zero/failed
exit status.

As requested in #11462 by @neutric as this produces confusing,
incorrect output.

Make `brew audit` complain about language module requirements because
they provide a crappy user experience compared to vendoring and we’re
not really fixing bugs in them any more.

Also check for `ENV.universal_binary` and `build.universal?`. The prior
is still required for `wine` and the latter should never be required any
longer.

This check for a nil `tap` is necessary because Tap.from_path(path)
will simply return a nil value in the event the tap path is invalid

Our CI images are already updated with it.
