virt: Add vboxguest driver for Virtual Box Guest integration UAPI
This commit adds the headers describing the ioctl API for the /dev/vboxguest device used by the Virtual Box Guest Additions in Virtual Box virtual machines. The driver providing the /dev/vboxguest device will allow Virtual Box Guest Additions features such as copy-and-paste, seamless mode and OpenGL pass-through.
