This prevents passing nested arrays to exec; the same thing is done in
safe_system.

The :force behavior for ENV.gcc has been the default for some time, and
was used to force vanilla gcc in case the gcc symlink pointed at
llvm-gcc; for ENV.clang, this doesn't mattera as clang is just clang.

Doing so was the result of a quick hack to fix the "deps installed as
upgrades don't get linked" bug, but it was a mistake. Instead, always
return the LinkedKegs entry as a Pathname object, and let callers be
responsible for checking that it exists.

These will be used to unify the label namespaces in embedded plists,
i.e. 'homebrew.mxcl.<formula>'.
plist_path returns the full path to a plist file located at the top
level of the keg; plist_path.basename can be used if just the filename
is needed.

This commit adds a `devel` entry to the DSL, allowing formulae to
specify an unstable branch.
`devel` takes a block, which should contain standard `url` and `md5`
fields (and `version`, if necessary). This must come after the standard
DSL fields.
This commit also migrates over all formulae currently using `devel` to
the new syntax, as well as formulae which used `head` for non-VCS urls.
The new syntax is also available for `stable` and `bottle`. `stable` is
an option alongside the old syntax. `bottle` replaces the old syntax.
Note that the @stable ivar in Formula has been renamed to @standard,
and the @bottle ivar has been renamed to @bottle_url.

Installing a formula via `brew install` may trigger upgrades of its
dependencies if the dependencies are installed but outdated. However, we
never unlinked the existing keg in FormulaInstaller#install_dependency
which caused the link step to fail.

Clang is vastly different than LLVM-GCC and is under active development. Using
Clang is a viable solution to formula that fail with LLVM and a suggested
recourse for users of XCode 4.2 or newer.

Previously, stripping arguments like `--HEAD` for dependencies failed because
that flag affects the installation prefix encoded into formula objects. The
previous implementation of `ARGV` filtering tried to contain all changes to a
single method call before the `FormulaInstaller` forks. This update spreads
things out a bit:
- The Homebrew `ARGV` extension adds a new method, `filter_for_dependencies`
which strips flags like `--HEAD`, yields to a block, then restores the
original contents of ARGV.
- The `explicitly_requested?` test, which returns true or false depending on
if a formula object is a member of `ARGV.formulae`, is now a method of
`Formula` objects.
- `FormulaInstaller` objects now execute the installation of dependencies
inside an `ARGV.filter_for_dependencies` block if the dependency was
`explicitly_requested?`.

This allows `brew audit` to inspect the head URLs, for example; until
now, that check was failing silently.

Also adjust output text slightly for prettiness.
A possibly useful side effect here is safe_system has a defined Exception (subclassing RuntimeError) now.
Mirrors can now be declared using the `mirror` method which works similar to
`depends_on` and takes the same arguments as `url`.
The formula class now has a public `fetch` method that cycles through the
mirror list if the downloader for the primary URL throws a `DownloadError`.
Other brew commands, like brew-fetch, also benefit from mirror support by using
this method.
ClosesHomebrew/homebrew#7574.
`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.
The compiler setting in the xcodeproj is overridden by the CC setting in the environment. This is a bit insane IMO since the xcodeproj itself has detailed decisions about what tools to use.
FixesHomebrew/homebrew#6406.
This is used with fails_with_llvm so that if GCC cannot be found (and we suspect this is the case with Xcode 4.2) the build will fail.
Quite possibly it should be the default.
