This patch adds support for 9p filesystem proxying over VirtIO. It can currently operate by connecting to a 9p server over a socket (VirtIO9PSocket) or by starting the diod 9p server and connecting over pipe (VirtIO9PDiod). *WARNING*: Checkpoints are currently not supported for systems with 9p proxies!
