dev: Add support for 9p proxying over VirtIO

Browse Source 
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!
