This patch implement HECI virtualization backend service based on virtio userspace framework. This service introduce a virtio-heci device model for DM, and can be enabled by DM parameter '-s [BUS NO],virtio-heci'. The HECI virtualization need both backend service in device-model and frontend driver in guest to work. Backend service mainly emulates HECI device's behaviors to satisfy frontend driver. They are based on virtio userspace framework. Currently, it is using two virtqueues, one is for TX and another is for RX.
