Having HOMEBREW_PATCHELF_RB set in the ENV,
will conditionally install patchelf.rb gem,
use patchelf.rb in the above mentioned methods.
The installed vendored gems are listed in .gitignore
to maintain a clean state.
We aren't going to vendor its dependencies because we already require
a systemwide installation of `rubocop` to work in your editor. This
avoids requiring users to manually do another
`gem install rubocop-rspec` to have their editor integration behave as
expected.
Rather than having to manually keep track of what version each thing in
here is and copy files around by hand on update let's use Bundler's
standalone mode and careful use of `.gitignore` to help us do it.
This means a `bundle update --standalone` will allow us to update all
gems in vendor.
We could consider vendoring other gems this way in future but I'd
suggest only doing this for gems with no dependencies or at least gems
with no native extensions. The only gem this applies to that we
currently use is `ruby-prof` and I'm not convinced it's widely used
enough to warrant vendoring for everyone. Perhaps that's another
criteria: it should be functionality that's used by non-developer
commands and/or normal Homebrew usage.
Homebrew's actually ended up using a fair few gems. While we want to
avoid Bundler at runtime (and this PR still does that, in fact uses
Bundler even less at runtime than it did before) writing our own version
to use at build-time seems redundant.
This smooths over the transition for users who have an existing
bundle config in this location due to having gems installed at the old
path.
Closes#2203.

GitHub now nicely generates a documentation site for us at
http://brew.sh/brew based on our docs folder. Optimise the output of
this and the GitHub docs directory for readability and the various user
groupings.
The vendor Ruby will be put inside `Library/Homebrew/vendor/portable-ruby/<version>`,
with a symlink `Library/Homebrew/vendor/portable-ruby/current` pointed to it.
In addition, a `Library/Homebrew/vendor/portable-ruby-version` will
track the latest version of vendor binaries.
This gives us version control on vendor Ruby and enables us to bump vendor
Ruby whenever needed such as security update.
