  Encapsulate the thread local storage into an egl::Thread class.
  
  Instead of having separate GetGlobal* functions, interact with the global
  objects through a single Thread object.  This reduces the number of TLS
  lookups in many EGL functions and allows the Thread object to be passed
  down to other objects if needed.
