bctest.py is only used as an import by bitcoin-util-test.py. There's no value in keeping it as a separate module, so let's merge them into a single module to keep building and packaging simpler. bitcoin-test-util is importable as a module, so if any future modules really want to import the code from bctest.py, they can import bitcoin-test-util and call the bctest functions by name.0.15
