Behaviour for git checkout was changed such that the update would fail because it refused to checkout files on to existing files in the working directory.
This was bad behaviour anyway, we should make efforts to keep any local modifications to the Homebrew checkout. Everything is neatly resolved if we just do a --soft reset.

This fixes reporting of which formulae changed in git versions where `pull`
output is not compatible.

When running `brew up`, if a mentioned formulae is also installed,
it will get a wildcard start at the end.
It makes it easier to see if any installed formulae is impacted.

The code was sucking. To the extent that maintenance was hard. It's a lot
easier to work with code that is sensibly split at sensible boundaries. So
now it is more like that.
But the refactor is minimal. Because we don't want you to have more merge
hell than absolutely necessary.
If you merge you will need to pay attention to brew.h.rb (as it is deleted)
and bin/brew (as command logic is gone). It will be painful, but you will just
have to help git out by moving any changes around manually.
Note compatibility.rb. It ensures that any function renames or removals don't
break anything. We're pretty serious about backwards compatibility. And that's
because we encourage you to hack around with the innards. And we couldn't do
that if we would then just make stuff disappear behind your back.
