tests: Update testing framework and begin reworking everything

Add in several new features like:
- Don't exit until the specific test function completes.
- Make it easier to run named tests from C++.
- Use a macro to find line number when calling test :: equal().
- Use a macro to do basic setup and cleanup between test functions.

Also update the version test while I'm at it.
