xcode: upgrade for Xcode 10.2.1 release

cmd/info: fix frozen pathname usage.

Fixes #6055.

python_virtualenv_constants: upgrade virtualenv to 16.5.0

Fix check_for_unsupported_macos() on outdated releases

utils: fix frozen string usage in odeprecated.

Fixes https://github.com/Homebrew/brew/issues/6053

Recent commit https://github.com/Homebrew/brew/commit/36dbad3922ad984f7c396a9757fe8ae9750c44b0 to default to frozen string literals (via `frozen_string_literal`) broke `check_for_unsupported_macos()` on outdated releases--due to attempted modification of a frozen string literal.

This breaks `install` and `doctor`.

It's like the change wasn't tested on an unsupported outdated release or something... :D

Adding a `+` prefix is apparently one way around this issue according to https://stackoverflow.com/questions/37799296/what-does-the-comment-frozen-string-literal-true-do#37799399. The change worked for me.

Add `*_to_slashes` methods to `compat`.

This is set by XQuartz and not needed information for us.

Unfortunately we cannot use `--frozen-string-literal` with Ruby 2.3 due
to https://bugs.ruby-lang.org/issues/12031 and our usage of ERB.

Endorse AdoptOpenJDK instead of Oracle OpenJDK

Freeze more mutable constants.

This commit changes the message that appears when Homebrew detects
that a Java requirement is unmet.

The new message will say:

```
Install AdoptOpenJDK with Homebrew Cask:
  brew cask install adoptopenjdk
```

And for Java 8:

```
Install AdoptOpenJDK 8 with Homebrew Cask:
  brew cask install homebrew/cask-versions/adoptopenjdk8
```

This rule adjustment is experimental in RuboCop as it may double-freeze
objects but this isn't an error (and freezing too much is better than
too little).

extract: Replace ARGV.named with args.remaining

test: kill all subprocesses on timeout.

Fixes #5885.
