merging/unifying test plugin code

* coverage/testplugin.py contains common test plugin options
  and pytest hooks (which don't induce "import py")
* coverage/nose_coverage.py contains a basic Nose Plugin
* test/test_testplugin.py contains a pytest-functional test
  and a nose-skeleton one.  skipped as appropriate.
