CI for FreeBSD

[asomers]

Would you be interested in running CI tests on FreeBSD? I volunteer to host it. I'm already hosting CI for the nix and mio-aio crates, and it would be no trouble to add this one. If you agree, all that you'll need to do will be to add the GitHub commit hooks.

Yes, I think we'd be happy to add freebsd CI to the run.

Ok, I'll set it up in polling mode. I don't think I need any special access to the mio repository in order to post status reports. Once it's working, I'll ask you to enable commit hooks.

Do you have an example of how it integrates? It would be nice to ensure that the CI passes for all PRs as well, similar to travis. One option is to have a "fake" travis build that actually delegates to the FreeBSD hardware.

Here's an example pull request: nix-rust/nix#663 . And if you look at https://github.com/nix-rust/nix/commits/master you can see the status posted for each commit. Nix uses bors, but otherwise it's similar to mio. BuildBot will post its own status notification alongside Travis and Appveyor.
