Also updates the bash-completion to ignore subdirectories, rather than
specific filename patterns.

Hides files with the extensions ".css" and ".erb" to ensure that the
brew-bot's support files don't show up in tab-completion.

Commit 3b5d7939d9a660a83e29a86e6bab234f3e9f2dcb added completion for
`brew link` options, but disabled completion of the actual command
itself.

The last make_relative_symlink was missing the mode argument, which
caused spurious linking under certain circumstances.

The symbol versions of :autoconf, :automake and :libtool only activate
for OS X / Xcode combinations that do not provide autotools.

Some programs fail where they would otherwise succeed if stdout or stderr is
closed. For example, using mpicc from the mpich2 formula:

    quiet_system 'mpicc', '--version'

Fails with:

    LLVM ERROR: IO failure on output stream.

While

    system 'mpicc', '--version'

Succeeds.

Add an ARGV.dry_run? helper method for '--dry-run'/'-n' now that

`brew link` can now be made to delete any conflicting files using
the --force argument. It also has a --dry-run option, similar to
git clean -n, which will list any files which would be deleted
without touching the filesystem.

When the first error pipe object is finalized, the underlying file
descriptor is closed, breaking the pipe between the build script and the
main Homebrew process. Keep a reference to this object so it isn't
closed.

This command was undocumented, only for autotools, and it is enough to do
`brew install foo -i` and then `./configure --help` in two steps.

* 4.3.3 is the latest on 10.7
* Give up if we don't know what the latest is (10.8 and beyond)

In 1.8, Pathname.find would work (and do nothing) if the
source path didn't exist. In 1.9 this throws an exception
instead, so check whether the file exists before trying.

Pathname is one of the basic building block classes in Homebrew, and as
such it is preferrable that `require`ing it does not drag in other
Homebrew code; thus avoiding circular dependency situations. Its
dependency on bottles.rb gave it an implicit dependency on formula.rb,
among other things.

0.9.2 includes the formula specs refactoring.

Signed-off-by: Jack Nagel <jacknagel@gmail.com>

Tools like `brew create` need to create and manipulate SoftwareSpec
objects. It is useful to be able to do this directly, rather than by
proxy through the special methods that serve the main formula DSL.

Now that a URL, version, and the (for lack of a better term) "specs"
associated with said URL (e.g. the VCS revision, or a download strategy
hint) are neatly bundled up in a SoftwareSpec object, it doesn't make
sense to pass them individually to download strategy constructors. These
constructors now take only the formula name and a SoftwareSpec as
parameters.

This allows us to move mirror handling out out of Formula#fetch and into
the download strategies themselves. While doing so, we adjust the mirror
implementation a bit; mirrors now assume the same "specs" as their
owner's URL. They are still only useable by the CurlDownloadStrategy,
but this provides a basis for extending mirror support to other
strategies.
