Subject: [PATCH 1/2] Allow test repos to be kept locally
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We no longer assume that the test repos don’t exist when we run run-tests.sh. This allows developers to choose to keep them, to allow them to run the tests more quickly.

- Add the test repos to the .gitignore.
- Check if the directory for each repo already exists, before trying to clone it.
- Do a `git pull` for each repo, to ensure that existing copies of repos are up-to-date.

Subject: [PATCH 2/2] Use specific commits when running tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This ensures that build breaks to any of the test projects don’t immediately cause rgbds tests to fail.

On clone, I’ve set it up to pull the commits since the day before the desired commit. Sadly, this will clone more recent commits that we’re not testing, but at least it ensures that the desired commit can be checked out. This is hopefully a good enough replacement for —depth=1.
