Allow XCode without the Command Line Tools to
work with homebrew, so it's not necessary
to register an Apple Dev ID and/or go to the
XCode prefs and download the CLT. Yay!
Further, this commit allows to use the CLT
solely (without the need for XCode).
Saves quite some megs.
(Some furmulae require xcodebuild)
Of course XCode together with the CLT is still
fine and has been tested on 10.7 and 10.6
with Xcode 4 and Xcode 3.
Only on Lion or above, tell the user about the options,
which are
- Xcode without CLT
- CLT without Xcode
- both (ok, it's not directly stated, but implicit)
So if no Xcode is found and we are on Lion or above,
we don't fail but check for the CLTs now.
For older Macs, the old message that Xcode is needed
and the installer should be run is still displayed.
If the CLT are not found but Xcode is, then we
print out about the experimental status of this setup.

'which' only returns a Pathname or nil, and doesn't care about anything
sent to stderr, so just silence it by default and combine the two
methods.

A common source of build problems on Xcode 4.3+ is outdated compilers,
usually when a user has installed over top of an old version and hasn't
installed the CLT. Since the compilers from the previous Xcode are still
around, brew doctor wouldn't complain.
This adds a hash containing a list of the canonical compiler versions
for supported versions of Xcode, and adds a check against that to determine
whether a given installation has any compilers which are out of date.

Also xcrun can only exist at /usr/bin/xcrun.
Most of these edges are non-buildable environments, but I didn't know that when writing it, so it may as well stay, since it still does make brew --env more correct.
Using xcrun as a proxy to execute the compiler tools is per its design. This means you can't treat ENV['CC'] as a path anymore, but I think I found the cases this was being expected and corrected them. It was not proper anyway to assume the variable was a path, it can be anything. Like a proxy. Like xcrun.
Also more thoroughly clear ENV.
Regexp#source retains escape sequences as is, so searching for formulae
like 'pure-ftpd' doesn't work.

Instead of returning a full list of results after parsing, yield and
print each result as it's found for a snappier user experience.

The v3 API currently lacks a search feature. Use the v2 API instead for
much faster pull request filtering.

When search can't find any local results, hit the GitHub API and search
the titles of pending pull requests. This will help people find the many
proposed formulae and prevent them from wasting time duplicating them.

Let's choose the first \d{2,} as the build number, as it is the most
likely to indicate significant changes, and we need something to use for
comparison when selecting compilers.

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.

Homebrew was attempting to check the version of gcc-4.0 and gcc-4.2 even
if they don't exist, causing `doctor` and `--config` to throw nasty
errors.
Also fixes the broken missing gcc-4.2 detection, which was confusing
Xcode 4.2 users.

For GCC and LLVM-GCC, '-v' is not a synonym for --version. When run
without any other options or arguments, it gives similar output, but it
is better to just parse the (terser) --version output.

Also adjust output text slightly for prettiness.
A possibly useful side effect here is safe_system has a defined Exception (subclassing RuntimeError) now.
`DownloadError` is an exception that download stratigies can throw to indicate
that a fetch was incomplete due to a failure in communication.
The `curl` method in `utils.rb` has been upgraded to throw a `DownloadError` if
something bad happens to `curl` execution.
