Made SPDYLAY_ERR_ZLIB FATAL error. Removed SPDYLAY_ERR_ZLIB_BUF.
Made SPDYLAY_ERR_ZLIB FATAL error. Removed SPDYLAY_ERR_ZLIB_BUF.

If SPDYLAY_ERR_ZLIB is encountered, zlib context is out of sync.
So we cannot further SYN_STREAM/SYN_REPLY/HEADERS frames.
I'm not sure we should send GOAWAY in this case.
So bail out with fatal error and drop connection for now.
