Motivation: The SPDY spec requires that all header names be lowercase (see https://www.chromium.org/spdy/spdy-protocol/spdy-protocol-draft3-1#TOC-3.2-HTTP-Request-Response). The SPDY codec header name validator does not enforce this requirement. Modifications: - SpdyCodecUtil.validateHeaderName should check for upper case characters and throw an error if any are found. Result: SPDY codec header validation enforces specification requirement.
