SPDY: store the length of frame instead of its whole size. The "length" value better corresponds with the specification and reduces confusion about whether frame's header is included in "size" or not. Also this change simplifies some parts of code, since in more cases the length of frame is more useful than its actual size, especially considering that the size of frame header is constant.
