test-bot: revise Step output transcoding and XML character filtering

We need to move the Snow Leopard fix down since Etc.getgrgid can't
handle a string.

Closes #31.

Fixes #20. Closes #23.

Makes `tap` re-runnable and unshallows when requested with `--full`.
Tapping with a different URL raises an exception.

The homebrew/core tap cannot be untapped with `untap` so running
`brew tap --full homebrew/core` is now a built-in way to get a full
clone of this tap without resorting to workarounds.

Closes #17.

When invoking `brew tap homebrew/core`, the input options will be like
`{ :clone_target => nil }`. This renders `Hash#merge` a dead operation.

It doesn't impact Homebrew itself, but could cause problem for
downstream projects Linxubrew/Tigerbrew when they adopt core/formula
separation.

Formulae are all in taps now.

Previously, superenv did not try to filter -I or -L flags
based on the list of requested dependencies; as a result, buildsystems
which opportunistically discover Homebrew-installed libraries were able
to link against them even under superenv.

This adds a list of all requested dependencies to the superenv environment,
and compares all -I and -L flags against those; any Cellar and opt paths
found which resolve to unrequested dependencies are filtered out.

Closes https://github.com/Homebrew/legacy-homebrew/pull/50462.

Add the first Google Analytics usage to monitor the command names that
are run by Homebrew.

Generally it seems user agents are all `software/version` but ours is
not. Also, set the user agent in a way that it's shared between Bash
and Ruby code.

Closes #6.

This reverts commit 0f60f76f.

* move shell completion scripts to where can be auto picked up

Let's use switching new remote as opportunity to put shell completion
scripts to where they should be and avoid git conflict during the process.

* add Library/Formula and Library/Aliases symlinks

Formulae and Aliases has been relocated to homebrew/core tap.
The symlinks are pointed to new location to keep backward compatibility.

* remove formula_renames and tap_migrations

They have been replaced by the json files in the core tap.

* update: set new remote

* bump Homebrew version to 0.9.9

Fixes Homebrew/homebrew#50651

We should remove PR lock files in the test tap rather than HOMEBREW_REPOSITORY.

This reverts commit 51e4e6490bda0d981afd1787a6392ab588b0601c. This did
not work as intended, as the `git` command is executed in the context of
the tap the current job operates on, never for Homebrew/homebrew itself.

Wipe everything from the Homebrew prefix except for the `Library/Taps`
directory to avoid having to refetch `homebrew/core` every time.

`install_name_tool` location depends on the location of the active developer
directory managed by `xcode-select`.
