All of these taps use Homebrew internal APIs (or will shortly) and we
autoinstall them all from `brew $CMD`. We should adjust our CI to ensure
that we never accidentally break these taps when making changes to core
code so that these taps can rely more on this core code rather than
having to e.g. vendor equivalent code that never changes on our end.

It defaults to being in $HOME but we override this meaning that we would
destroy the cache every time.

Check the syntax for Homebrew/brew and don't bother for taps.

This is not a command designed for end-users.

This adds >1m to every build on every node and it can't actually be
affected/fixed by formula PRs.

This job takes almost a minute and it's not useful for all core taps
to run this.

We're not really getting any more PRs here and this code makes this file
harder to follow and refactor.

This means that we do not need to read formulae or evaluate Ruby at
upload time.

Closes #1028.

Replace `homebrew` with `brew`, `homebrew-core`, or `legacy-homebrew`
depending on context.

Noted, `brew tap foo` will not fail if the tap is already installed.

Pulls 'brew linkage' in to main brew repo as a dev-cmd, and has test-bot
use it to detect dylib breakage, which usually means a revision bump is
needed. Checks all dependents, not just those with a 'test do' block
defined, since we can do this without formula support.

https://github.com/Homebrew/brew/commit/e70a3552d3faddd0afd2535a03c31b8c50be901a seems to have
exacerbated the problem where taps stick around and then `brew uses` gets executed
on a whole host of taps, which is currently breaking almost every PR for formulae
that would be used cross-tap, as well as causing lengthier CI builds.

Examples from the last week or so include sqlite, V8, protobuf, and so on. Whilst it
may be true that cross-tap formulae failing can show problems that need looking at,
a lot of the time the failures are unrelated to the build in question and just
leave contributors confused on what needs to be done, or why their PR is failing
for something that seems entirely unrelated.

You can see the taps failing to vanish locally by doing something like:

```
brew tap homebrew/fuse
brew tap homebrew/versions
cd $(brew --prefix) && git clean -ffdx --exclude=/Library/Taps/
brew tap
...
homebrew/core
homebrew/fuse
homebrew/versions
```

This is a very simple proposal to handle the problem, but there's no real reason
I couldn't write this functionality into untap itself and then we call that in
test-bot. Just didn't necessarily want to jump immediately to expanding the untap
command to solve what is more-or-less a CI problem.

Also enables sandbox for --interactive and --debug use of install
and test, using automatic retention.

Closes #92.

We're not sure this is working as it was intended to, and the primary
end product so far has been making every Ruby 1.8.7 build, which is the Ruby
we use on Mavericks for compatibility, take 5-15 minutes longer per build
than 2.x Rubies.

Cumulatively this is responsible for the vast majority of CI slowness over the
last couple months as Mavericks plays catch-up and everything else waits for it
to do so.

We may revisit this in future, but for now the harm is greater than the "risk".

This technically reverts https://github.com/Homebrew/brew/commit/7b26c585c2a26ec0dad201852ca4934c77fcc493.

Fix bug introduced in a2c23dfe. Moving
this method apparently made it inaccessible from `Homebrew::Step`.

The method `fix_encoding!` is private to `Homebrew::Step` but is also
required by the `Homebrew.sanitize_output_for_xml` method for truncating
overly long logs. Move `fix_encoding!` into the `Homebrew` module to
make it accessible from both this method and the `Homebrew::Step` class.

This amends commit 343091c8.
