Subject: [PATCH] test_runner: give the root test a harness reference

This commit replaces the 'coverage' reference inside of the Test
class with a more generic harness reference which includes
coverage. This will let the root test more easily track process
level state such as code coverage, uncaughtException handlers,
and the state of bootstrapping.
