s/REFUSED_STREAM/RETRY_STREAM The definition of REFUSED_STREAM is somewhat contradictory with the definition of the word refused.  The word refused is defined as: indicate or show that one is *not willing* to do something (https://www.google.at/).  The definition of REFUSED_STREAM in Section 7 references section 8.1.4 which says that a REFUSED_STREAM is safe to retry.  In other words the server is actually *willing* to process the stream, but *currently unable* (e.g. because the client overran settings and so the client needs to retry the stream with the new settings.)
