Motivation: Related to issue #4185. HTTP has the option to disable header validation for optimisation purposes. Introduce the same option for SPDY headers. Also, optimise SpdyHttpEncoder by allowing the user to specify whether or not the encoder needs to convert header names to lowercase. Modifications: Added flags for validation and conversion. Result: SpdyHeader validation and conversion can be disabled.
