Stefan Hajnoczi 580b6b2aa2 dataplane: use the QEMU block layer for I/O 
Stop using a custom Linux AIO request queue from ioq.h and instead use
the QEMU block layer for I/O.

This patch adjusts the VirtIOBlockRequest struct with fields needed for
bdrv_aio_readv()/bdrv_aio_writev().  ioq.h used struct iovec and struct
iocb, which we don't need directly anymore.

Modify dataplane start/stop to set the AioContext on the
BlockDriverState.  We also no longer need to get the raw-posix file
descriptor.  This means image formats are now supported with dataplane!
