Fix the `brew tests` problem caused by core/formula separation.

All formulae are in taps now.

Update the description update logic, since now all formulae are in the taps.

Update the report logic, since now all formulae are in the taps.

We don't need to migrate the tapped formulae from symlink-based to
directory-based structure any more.

Instead, we add core tap install check for `brew update-report` which
will be invoked by `brew update`.

Also make `Homebrew/homebrew` as an alias of this tap to keep
backward compatibility.

It will be auto installed whenever necessary.

* Count .DS_Store disk usage but not file count.
* Count symlink's own disk usage instead of ignoring it.
* Count hardlinks disk usage only once.
* Add testcase.

Don't use ensure to do the final check because it won't affect the

Calling `compute_dependencies` will make sure both requirements and
dependencies are expanded, so that any referenced taps can be
auto-tapped. Prior to this commit only dependencies were expanded for
the sake of auto-tapping, so dependencies of requirements would cause
installation to fail whenever a tap unavailable exception was
encountered.

The API used (`Net::HTTP::Post`) does not handle basic authentication
credentials in the same way as `open` so fix both cases so they work.

Also, do some general usability tweaks to point out to people what could
be wrong with their tokens or credentials to help them debug.

ngrok 1.x has been sunset by upstream. It no longer functions for non-authenticated
users and as of April 4th will stop working entirely.

Upstream has also clarified there are no plans or intentions to make 2.x
open-source, which means we cannot carry that upgrade in core Homebrew, partially
for legal reasons.

If you wish to use the closed-source 2.x release you can still install it
via Homebrew in a couple of ways:

You can either `brew install homebrew/binary/ngrok2`
OR:
You can install it via the Caskroom, with `brew cask install ngrok`.

This can become handy when we separate core code and formulae. For
example, we could use `cd $(brew --repo homebrew/core)` to go to core

Since we support `apply` DSL in the `patch` block, external
patch files could be any compressed archive. As result, it
could introduce dependencies like xz, 7z etc.

Add the resource of ExternalPatch to dependency_collector, so
we could track these resource dependencies.

* Use `ENV/scm/git` to check whether git is installed.
* Use `brew install git` to enforce pre-install checks such as sudo
  check.

`/usr/bin/<tool>` will be a popup stub under such configuration.

The idea is to let `scm/git` to handle all of git location resolution
throughout Homebrew codebase.

`Library/ENV` like `Library/Homebrew` is part of Homebrew basecode. It
should be able to be accessed during the `brew tests`.

By adding HOMEBREW_ENV_PATH variable, we allow test suit to locate these
codes.
