Disabled handling of headers without a colon. Starting with nginx 0.1.29 (509:9b8c906f6e63), header names not followed by a colon and a value were allowed. Such headers were interpreted as headers with an empty value. With this change, such headers are unconditionally rejected. Requested by Maksim Yevmenkin.
