TAP is a text format for test results. Parsers for it are available in many languages, making it easy to consume. I want TAP output from our protocol tests because the Hive wrapper around them needs to know about the test names and their individual results and logs. It would also be possible to just write this info as JSON, but I don't want to invent a new format. This also improves the normal console output for tests (when running without --tap). It now prints -- RUN lines before any output from the test, and indents the log output by one space.
