This mostly affects response.headers['cookie'] for test requests. Use response.cookies instead.

Diverge Metal implementation from Rack::Cascade since we want the last app to return its headers and body if the status is a 404.

Add a repair_helper to repair changes to the validations inside validations_test.rb [#674 state:resolved]

Many of the tests in validations_test would add a new validation to
models.  However, only Topic was being reset with a fairly aggressive
clearing of all validations.  None of the other models being used however
were recieving the same treatment.  Now we use repair_validations(Topic)
for the whole test case because most test cases use Topic and then the
block form of repair_validations(<other_models>) inside any tests that use
other models.

This reverts commit e8c19154.

Reasons :
- ActionPack tests run very slow
- Gem.searcher hanging for long time when extension is nil

No freeing Result objects causes the MySQL driver to free result sets
at undefined times, this can lead to erratic performance in your
application.
