Adds the Virtual Services framework and core protocol code. The Virtual Services framework provides a bus for generic inter-vm communications using a high level abstract model. The vservices bus provides support for both HLOS and embedded C clients and servers, allowing VMs to communicate in a common OS independent manner. The vservices bus and services over it are hot-plug capable and can support a wide variety of use cases, including device virtualization using virtual device protocol (classes) and drivers, similar in concept to USB or virtio.
