Taking in a filehandle gives the user quite a bit more freedom on how to handle boot log output. They can set up a kqueue watch on it and redirect output somewhere else etc etc. The implementation for this has us take in a new BootLog type that has two options: 1. .file, which is analogous to what we had prior. Just provide a URL and a true by default append field. 2. .fileHandle which is the new addition. Can pass any fd that is writable, and the VMM should write serial console output to it.
