FormulaInstaller now attempts to take a lock on a "foo.brewing" file for
the formula and all of its dependencies before attempting installation.
The lock is an advisory lock implemented using flock(), and as such it
only locks out other processes that attempt to take the lock. It also
means that it is never necessary to manually remove the lock file,
because the lock is not enforced by I/O.
The uninstall, link, and unlink commands all learn to respect this lock
as well, so that the installation cannot be corrupted by a concurrent
Homebrew process, and keg operations cannot occur simultaneously.

Similar to the LinkedKegs record, we write a symlink for installed kegs to PREFIX/opt.
Unlike the linked-keg record, unlinking doesn't remove the link, only uninstalling, and keg-only formula have a record too.
The reason for this addition is so that formula that depend on keg-only formula can build against the opt directory and not the cellar keg. Thus surviving upgrades.
To enforce this fix_install_names and built were adapted to use the opt path.
Standard kegs also create an opt symlink so that caveats can now refer to the opt directory and thus provide steps that survive upgrades too.
Thus the choice of /opt. It is short, neat and the right choice: POSIX dictates that opt is for stand-alone prefixes of software.

In fixing this I also made it so that ARGV.kegs will return the LinkedKeg if the symlink is set. Which is almost always is. This neatly avoids most multiple-kegs issues.
Fixes Homebrew/homebrew#10685.

`rack` is a commonly used alias for `formula.prefix.parent`---so common that it
gets defined and used quite a bit. This patch makes `rack` an official method
of the `Formula` class.

Finder activity such as moving the position of an icon can create an unexpected
.DS_Store file in a Cellar directory. This causes `brew remove --force` to throw
an error that is reported as
Error: Directory not empty - /usr/local/Cellar/<formula>
This fix avoids that error, by calling rmtree rather than rmdir.

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.
