/**
* This file implements the RIL worker thread. It communicates with
* the main thread to provide a high-level API to the phone's RIL
* stack, and with the RIL IPC thread to communicate with the RIL
* device itself. These communication channels use message events as
* known from Web Workers:
*
* - postMessage()/"message" events for main thread communication
*
* - postRILMessage()/"RILMessageEvent" events for RIL IPC thread
* communication.
*
* The two main objects in this file represent individual parts of this
* communication chain:
*
* - RILMessageEvent -> Buf -> RIL -> postMessage() -> nsIRadioInterfaceLayer
* - nsIRadioInterfaceLayer -> postMessage() -> RIL -> Buf -> postRILMessage()
*
* Note: The code below is purposely lean on abstractions to be as lean in
* terms of object allocations. As a result, it may look more like C than
* JavaScript, and that's intended.
