Run Regression Test Suite

This module calls down into individual test cases via subprocess. It will
forward all unrecognized arguments onto the individual test scripts, other
than:

    - `-extended`: run the "extended" test suite in addition to the basic one.
    - `-win`: signal that this is running in a Windows environment, and we
      should run the tests.
    - `--coverage`: this generates a basic coverage report for the RPC
      interface.

For a description of arguments recognized by test scripts, see
`qa/pull-tester/test_framework/test_framework.py:BitcoinTestFramework.main`.
