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.

Xcode 3.2.6's build of clang is 77, which wasn't being matched by the
clang_build_version regexp.
ClosesHomebrew/homebrew#8796.

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.
Look in /usr/bin because all versions of Xcode install it to /usr/bin now and this allows us to support Xcode-less installs of Apple's developer tools.
When running `brew up`, if a mentioned formulae is also installed,
it will get a wildcard start at the end.
It makes it easier to see if any installed formulae is impacted.

Moved snow_leopard_64? to compatibility and replaced it with
a function MacOS.prefer_64_bit?. This method is in a better
place and has a better name once Lion comes out.
FixesHomebrew/homebrew#4710
The code was sucking. To the extent that maintenance was hard. It's a lot
easier to work with code that is sensibly split at sensible boundaries. So
now it is more like that.
But the refactor is minimal. Because we don't want you to have more merge
hell than absolutely necessary.
If you merge you will need to pay attention to brew.h.rb (as it is deleted)
and bin/brew (as command logic is gone). It will be painful, but you will just
have to help git out by moving any changes around manually.
Note compatibility.rb. It ensures that any function renames or removals don't
break anything. We're pretty serious about backwards compatibility. And that's
because we encourage you to hack around with the innards. And we couldn't do
that if we would then just make stuff disappear behind your back.
If set, use "HOMEBREW_EDITOR" when editing a single file, or multiple
files in the same folder.
Note that this setting does not affect `brew edit`, since opening
all of Homebrew at once requires an editor with proper project support.
"brew --env" will set up a build environment and then dump certain ENV
variables (CC, CXX, LD, CFLAGS, CXXFLAGS, MAKEFLAGS).
If any of CC, CXX, LD are symlinks, now also output the target compiler.
(Typically these will be symlinks from eg /usr/bin/cc to /usr/bin/gcc-4.2).
This is a diagnostic command which may be merged into --config, turned
into an external command, or removed if it doesn't turn out to be useful.
Homebrew will now use the svn binary pointed to by HOMEBREW_SVN if set,
use a Homebrew-installed svn if present, finally falling back to the
system-provided svn binary.
If a formula (mplayer) requires a newer version of Subversion than what
Leopard provides, it can use the "StrictSubversionDownloadStrategy"
download strategy to warn the user.
These changes also fix an issue with forcing exports not working on a
stock Leopard subversion, but letting the user either specify a specific
binary or install Subversion via Homebrew and pick that up instead.
