Use `Formula.factory dep.path` instead of `Formula.factory dep.name` so that
non-standard dependencies specified as URLs or paths can be handled properly.
In later XCodes, gcc is a symlink to gcc-4.2 which is itself a symlink
to llvm-gcc, so it is necessary to resolve multiple symlinks.

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.

This version number is arbitrary, and only used to differentiate versions
in bug reports.
There have been enough changes to compiler detection since 0.8 that it makes
sense to bump the version here.
Current warnings contain a mix of variable names with a '$' prefix and
without; most documentation omits the '$', so drop it.

- Fix ENV.libxml2 to update CPPFLAGS rather than CFLAGS
- Methods ENV.{gcc*,llvm,clang} now reset CPU-specific optimization
flags on every call.

Rationale: some software (e.g. GNU Coreutils, GnuTLS 3.x), have started
distributing _only_ xz-compressed tarballs. There is no system XZ
utility provided by OS X, but it is necessary so that we can continue to
provide formulae for this software.
If XZUtils isn't installed, we abort and prompt the user to `brew
install xz`.
The `xz` command itself doesn't do any untarring, so we write the
decompressed archive to stdout and pipe it to tar.
Several issues have been caused by conflicts between the options
Homebrew passes to curl and those read from $HOME/.curlrc. Passing '-q'
will force curl to ignore settings in that file.

When investigating issues, one might want to see exactly what curl is
doing behind the scenes. Setting HOMEBREW_CURL_VERBOSE will cause the
'--verbose' flag to be passed to all invocations of curl.

This can be made more robust in the future when we stop throwing away
the ':build' type flag in Formula#depends_on.

Should help advert confusion surrounding the "could not find gcc 4.2.x" message
recieved by Lion users running the latest version of XCode.
FixesHomebrew/homebrew#8876.
The ARGV filtering would strip `--HEAD` from dependency installations,
then proceed with trying to install the dependency from the latest
version in the formula. This causes an error if the latest version is
already installed, so check to see if formula is installed before
performing the installation.
