Enable coverage test for unit tests

Enabling for vmtest will take a bit more thought, as well as,
combining results all test runs. HTML reports later too. Additionally,
teach bzr to ignore .coverage directory where runtime coverage data gets
written to.

To run:
   make unittest COVERAGE=1
or
   make coverage

The 'coverage' target will grow to support coverage testing all tests.
The default options for nose coverage opts can be overridden via
the 'coverageopts' environment variable.
