Message : Add gl::ErrorSet and angle::Result. gl::ErrorSet can handle errors and is accessible from ContextImpl. It allows the implementation to mutate the error set without using the gl::Context directly. angle::Result is the faster POD return value class. It should generate optimal code. It can also be used seamlessly with the ANGLE_TRY macro. Also introduces an internal enum as a workaround for generating and consuming errors in the back-end. When the internal enum is used as an error return value the error is not consumed in the front-end. This is a temporary workaround only.
