To allow
depends_on :x11 => :optional
and friends to work as expected, make requirements record any tags and
add special handling to the X11Dependency to record both a minimum
version and additional tags.

ComparableSet only allows a single object of a given class,
choosing the object with the greatest value. This was mainly created
for Requirements, so that, e.g., two X11Dependencies of differing
strictness don't both end up in the same requirement set.

Clarify the error message arising from XCodeDependency so that users know
XCode.app is needed and that just installing the CLT does not count as
"installing XCode".
XQuartz isn't added to the default library paths so if something is
linked against a Homebrew libpng then it doesn't work against the
XQuartz libpng. The CLT provides X11 on Lion so don't request users
install XQuartz if it isn't needed on Mountain Lion.
FixesHomebrew/homebrew#14325.
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.

In order to better support Xcode-only systems, where X11 libs and
executables live under /usr/X11 but headers live in the SDK, move the
x11_* helper methods into a new module.
This allows us to keep some of the CLT/Xcode-only and Apple X11/XQuartz
logic hidden from outside code, like ENV.x11.
Since Apple's X11 is actually XQuartz, name the module "MacOS::XQuartz".
conflicts_with is a thin wrapper around Requirement which simplifies
marking conflicts between formulae.

All versions of OS X prior to Lion shipped with some version of Open-MPI, but
without working compiler wrappers for Fortran. Homebrew currently has two
formulae that can supply this software: open-mpi and mpich2.
This commit adds a `MPIDependency` Requirement that can be passed one of four
values when constructed:
:cc, :cxx, :f90, :f77
This will ensure the `mpi<value>` compiler is available and working. For
example, if `depends_on MPIDependency.new(:cc, :f90)` is used, the Requirement
will search for working `mpicc` and `mpif90` wrappers.
If the required wrappers cannot be found, an error message will be displayed
that prompts the user to install one of the Homebrew formulae that provides
MPI.
For each language passed to a MPIDependency Requirement, environment variables
be will set that point to the compilers.

Because of some quirks in how formulae are loaded, DSL methods invoked
in the class definition are called multiple times. This results in, for
example, duplicate dependencies and requirements.
Code that iterates over requirements and takes some action for each can
thus repeat things that shouldn't be repeated, like appending to
environment variables.
Make DependencyCollector's external_deps a Set, and define eql? and hash
on Requirement to prevent these duplicates.

Rather than doing type introspection in build.rb, just define a method
to perform the necessary environment setup for Requirements.

Some times the module to import is different than the module to install
when dealing with external dependencies. This change allows an optional
import name to be specififed when it is different from the module name.
