CONTINUATION frames are tricky, because individual header fields can be split between HEADERS frame and CONTINUATION frame, or two CONTINUATION frames. Therefore, some extra logic is needed when header parsing returns -EAGAIN, as we may need to remove the CONTINUATION frame header from the stream before proceeding with headers parsing. This commit implements the above logic and additionally adds more checks to detect when CONTINUATION frame is expected. Not receiving a CONTINUATION frame when expect should be treated as a protocol error. Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
