  Proliferate gl::Context.
  
  This enables a few small things: it will enable making the platform
  a property of the Display rather than a global. The same goes for the
  global logging annotator. Also it ensures all back-end implementations
  have access to the GL / EGL state when available.
  
  Also introduces a smart pointer helper class to angleutils for objects
  that prefer to be destroyed with a context (gl::Context/egl::Display)
  parameter. We were using std::unique_ptr in a few places that would
  not work well with these objects.
