If a keg has been uninstalled via `rm -rf <keg>`, and a user tries to
reinstall it without `brew unlink`ing it first, it will fail to link as
the LinkedKegs entry still exists. This isn't desirable, and the user
should be able to reinstall the same formula on top of the old, dead
symlinks without problems, so let's just remove the LinkedKegs entry if
it matches the one we are installing anyway.

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.

This reverts commit 2eabe2cbc84649696aeb6fa842a70f3794955597.
When Keg#unlink looks for symlinks relative to the keg, it can hit false
positives that actually belong to a different keg and unlink them
anyway. This breaks our "force identical directory symlinks to be shared
real directory" case.
This may be a problem in general with the unlinking code and should be
investigated.

If a formula makes it all the way to the actual install step, it is safe
to unlink the keg before linking; this will prune dead symlinks in the
case where a keg was removed with `rm -rf <keg>` but not unlinked with
`brew unlink`.

Symptom: If no python/ruby/perl is in your path, then `which x`.chomp
returns an empty string and `unless ""` is still true. So, N/A is never
displayed. Instead, ruby's Pathname.new("").realpath returns the cwd.
(I consider this realpath behavior a ruby bug) Fix: use empty?

Now we handle some things more explicitly and in the process get rid of
the blanket rescue on the mktemp block, which is something of an
antipattern.
By unloading the class *after* determining the version, we avoid the
case where the class had previously been unloaded but Formula.factory
failed, and trying to unload the nonexistent class results in a
NameError. Doing it this way, we avoid having to rescue NameError and
thereby avoid hiding other cases where it may occur.
We also rescue TypeError which gets us past a few more bad formula in
the history in some instances.

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.

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

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.

This is silly, but I am no Rubyist and I don't have time to
figure out why Formula.factory(foo).url works as expected but
Formula.factory(foo).version does not.

This will be useful for shell tab completion when something like `brew
install <formula> --version <version>` is implemented.

Rather than regex the output of `git show <rev>:<path>`, we write the
output of `git cat-file blog <rev>:<path>` to a temporary file, and then
operate on it just as we would a normal formula.
I haven't observed any speed difference. `git cat-file blob` is faster
than `git show`, but the "slow part" is still the git-rev-list
invocation. But really it's pretty fast overall.

When multiple kegs are installed, `brew info` marks a keg with an
asterisk if f.installed_prefix == keg, but this is only true if either
HEAD or the newest version of the formula is installed. This isn't
always useful, so let's mark the currently linked keg with an asterisk
regardless of the version.
Obviously, keg-only formula will never be marked, but this is probably a
feature. When multiple keg-only kegs exist, chances are that they are
each being utilized by something, so there isn't really a "used" and
"unused" version.
