Virtproxy relies on routines defined within qemu-vp which mirror various
i/o related operations in qemu to provide similar functionality for the
guest daemon. When building virtproxy as part of qemu rather than
qemu-vp we need these definitions to provide those functions in terms of
the original qemu functions.

odd alignment again.
