Two methods:
* `Utils.git_available?` checks whether git is installed.
* `Utils.ensure_git_installed!` installs git for users who don't install
Xcode or CLT.
By directly modifying the results array with
`results[i] = "#{name} (installed)"`, it appeared on successive
iterations that the canonical name was no longer in the array, so
aliases were not removed.

For update, all formula loading need to be secured by `rescue`.
Otherwise it's easy to crash `brew update` for vasty reasons, e.g.
new Formula DSL.

If the user's working copy is *not* on the 'master' branch, the revision
recorded after the update to the 'master' branch is not the one of the
updated 'master' branch but that of whatever the user's current branch
is. This tends to be not very helpful.
This change records the revision *after* the update to the 'master'
branch, but *before* switching back to the user's current branch prior
to the update, effectively causing the report to show changes to the
'master' branch.

Fixes test-bot mishandling of optional cross-tap dependencies. Without
this change, since formula.stable.deps includes the optional dependencies but
formula.recursive_dependencies does not, test-bot was trying to select a
compiler for an untapped formula, which raised an error.
Our suspect handling of optional dependencies was exposed by Homebrew/homebrew#43145 /
7184348e822d6745d8a103de104ff9626536bf1e.

Long term it would be nice to sandbox everything that writes to DerivedData
but it is essentially a cache directory of sorts.
The downside of allowing stuff to write there particularly is that DerivedData
is notoriously bad at getting cleaned up, so if you do a lot of Xcode-using
installations very quickly, you can chew your disk space up.

Use an exponential back-off on the sleep and try the fetch more times.
Hopefully this will mean that we spent less time waiting for Bintray.
