/**
* Holds global state for an instance of ZeroTier::Node
*
* I do not believe in mutable static variables, period, or in global static
* instances of objects that don't basically represent constants. It makes
* unit testing, embedding, threading, and other things hard and is poor
* practice.
*
* So we put everything that we would want to be global, like Logger, here
* and we give everybody this as _r. The Node creates and initializes this
* on startup and deletes things on shutdown.
