Mostly this makes the tap code work again with all of the changes that have happened to the block drivers recently. We now use a shared page per VBD (to the driver), and handle control information through the store. The taplib interfaces have changed to be based around per-vbd data structures that you can attach arbitrary handlers for. There is also initial code for a user-level blockback driver, which aims to get around the use of loopbacks for file-based vbds. Still plenty of work to do here -- this is a working incremental checkin and I'm away from this for the next four weeks. Signed-off-by: Andrew Warfield <andrew.warfield@cl.cam.ac.uk>
