add some more code

This adds a basic "worker" program.

You can now do something like

    ./server &
    ./worker &
    ./client ci_run URL REV

and the server should pass a message to worker, after which it should
clone the repository at URL, checkout REV, and try to run the CI script.

It's extremely unfinished: I need to sort out the graceful shutdown, how
the server manages workers, etc.
