In addition to the "SoC/CLI" implementation that is already included, OpenThread needs a Network Control Processor (NCP) implementation to facilitate applications where the Host Controller is logically separate from the controller that implements the Thread stack (Which is the NCP). This task also necessitates the definition of the protocol that the Host Controller and the NCP use to communicate with each other. This commit represents a functional starting point for both of these. The initial name of the line protocol is "Spinel" (Named after the [gemstone][1]). The long-term goal is to standardize the Spinel protocol to be the official line protocol for host-to-NCP comunication for Thread. A [draft of the Spinel protocol document][2] is included in this commit. At this point everything is subject to change, but as-is the protocol has been demonstrated to work fairly well. The NCP implementation in the has been tested and is working well enough for basic connectivity, but it is far from complete. A Host implementation is not yet provided in the tree, but will eventually be included. A separate host implementation for Linux has been written and is anticipated to be released as a separate project over the next few weeks.
