Usually, the "foo-version already installed" error is printed by
FormulaInstaller. However, if an up-to-date formula that has outdated
deps is passed on the command line, we proceed to upgrade the deps and
then print a message saying that the formulae given on the command line
is already installed.
Catch this earlier, when the outdated list is being populated, print an
appropriate message, and skip the up-to-date formula.

This serves the same purpose as similar code in FormulaInstaller, but we
duplicate it because we do the dependency expansion in an ad-hoc fashion
here.

The heuristic used by the default version comparison is simple. A
version string is scanned for strings of digits, split into an array of
these strings, and then an element-wise comparison is done.
This fails when presented with something like
Version.new("1.0.0beta7") <=> Version.new("1.0.0")
because the first three digits match, and the fourth digit of the
receiver (7) is greater than the assumed fourth digit of the parameter
(0).
Fix this by defining an element-wise comparator on a new VersionElement
class. This allows us to correctly compare "alpha", "beta", and "rc"
style version strings, and keeps the logic out of the main version
comparison.

The heuristic for determining whether something is installed changes
from "f.installed?" to "f.rack.exist? and f.rack.subdirs.length > 0" in
order to properly consider outdated formulae.

This will allow us to do comparisons like
if MacOS.version >= :lion
and hopefully deprecate the MacOS.<name>? family of methods, which are
counterinitutive.
A version scheme is a class that inherits from Version and reimplements
Version#<=>. This will allow formulae to specify a custom comparison
method that will be used instead of the default, for cases where the
default is insufficient.
In FormulaInstaller#install, needed_deps is created without first
filtering ARGV for flags like --HEAD. In practice, this means that
sometimes needed_deps will contain dependencies that are actually
already installed; --HEAD causes Formula#installed_prefix to differ and
thus checking Formula#installed? will result in false negatives.
This can trigger weird bugs; for example, Homebrew/homebrew#10380, where the "Installing
foo" header is displayed even though no dependencies were previously
installed.
Fix this by filtering ARGV before testing for installed dependencies,
and do the same for requirements to maintain symmetry, and because some
requiremnts check Formula#installed? as well.

Currently FormulaInstaller "forgets" about the requirements of
dependencies, as dependencies are recursively expanded by the first
FormulaInstaller instance, and then ignored by subsequent instances to
prevent duplicate installation attempts. These requirements then have
their messages displayed, but the fatal check is skipped and thus no
exception is raised.
Now that we have Formula#recursive_requirements, we can mirror what we
are doing with dependencies and recursively expand requirements up
front.
While at it, fix a bug in determining Requirement equality that resulted
in unique requirements being eliminated from a formula's set of
recursive requirements.

Apple's X11 is XQuartz, but this can be confusing, and is ultimately

-D is now the switch for diagnostic-dumps. Let it be so.
Shows how long each doctor method takes in a sorted table at end. I used this to move the two slowest methods to the end of the doctor run so that as much useful information can be shown as quickly as possible.
Also now possible to specify on command line which tests should be run.
This was slowing down every instantiation of brew significantly.
Hopefully doesn't break anything that had become accustomed to not having to require 'formula' or 'keg'.

As options are stored in an object owned by the eigenclass of a formula,
options defined in the Formula#options method can be added multiple
times if the formula is instantiated multiple times.
Store them in a set to prevent duplicates.
