Combined with https://github.com/Homebrew/homebrew-test-bot/pull/247
this will test Homebrew's use of frozen strings in CI. After this we
will then enable it for Homebrew developers and eventually all Homebrew
users.
- search_for_cask in missing_formula renamed to is_a_cask_reason
- is_a_cask calls new getInfo method in cask/cmd/info.rb to return info
string
- self.info in info.rb now calls getInfo and puts return value
- added ohai_title to return the ohai printout for only titles, so that
ohai printout could be added to the getInfo return string without
calling puts.
- refactored ohai to use ohai_title
- updated info_spec.rb cask info test to be more specific when
matching stderr.
- is_a_cask_reason will respect 'silent'
- refactored print_caveats to return instead of print
For some reason Mojave needs the SSL args always set otherwise this
will always fail waiting for interactivity.
Also, while debugging this I noticed that `utils.rb` had a failure
expecting an integer so fix that too.
In February 2013, Rubygems 2.0.0 deprecated [1] the `--[no-]ri` and `--[no-]rdoc` options, replacing them with the new `--[no-]document` option.
Almost five years later, Rubygems finally dropped support [2] for the long-deprecated `--[no-]ri` and `--[no-]rdoc` options.
This removal causes `bundle install` to **fail for fresh Homebrew checkouts** if Rubygems 3.0.x or newer is installed, which will happen if the user runs `gem update --system` on Ruby 2.3.0 or later. [3]
This also affects the system Ruby built into macOS 10.13 and 10.14.
Steps to reproduce:
```
$ sudo /usr/bin/gem update -N --system
[…]
Installing RubyGems 3.0.2
ERROR: While executing gem ... (Errno::EPERM)

$ cd "$(mktemp -d)"
$ git clone --depth=1 https://github.com/Homebrew/brew.git
[…]
$ cd brew
$ export HOMEBREW_PATH=bin # in case shellcheck is not installed
$ bin/brew style Library/Homebrew/extend/ENV/std.rb
==> Installing or updating 'rubocop' gem
Error: invalid option: --no-ri
```
(Note: The above steps will not touch an existing Homebrew installation, and won’t even require Homebrew to be installed.)
This commit replaces the deprecated options with the new `--no-document` option, which has been around since Rubygems 2.0.0. It is therefore safe for use on all supported platforms.

This provides a more consistent version for `rubocop` than relying on
`Homebrew.install_gem_setup_path!` (and we really want `brew style` to
provide consistent output).
Adjust the rules based on the current codebase. Remove various enable,
disables and default values that are unnecessary. Add more comments
explaining why. Make minor changes needed to enable a few more rules.
