Support contributions to codebases without canonical Git repository

[ddimtirov]

Some widely-used codebases do not have cannonical Git repository. For example: Linux Kernel (uses Git, non cannonical repo), SQLite (does not use Git)

One way to facilitate contribution to these is to maintain internal mirror and use patch oriented workflow (#61).

Although this would definitely be nice-to-have, current adopters have not requested non-Git support. As for other hosts (GitLab, etc.), this has been implemented in #1042. Meanwhile, non-Git projects such as SQLite often have a mirror that does use Git (https://github.com/sqlite/sqlite).

Feel free to re-open as a discussion if you'd like to see this implemented 🙂
