Tatsuhiro Tsujikawa 82e20192d8 Added functions to process received SETTINGS frame.
Now remote and local settings are stored separately.
The initial window size is included in SETTINGS frame, all active stream's
window sizes are now updated.
Removed the initial_window_size member from spdylay_stream because
it is the same as remote_settings's initial window size.
