Performs post-process of HTTP Upgrade request. This function can
be called from both client and server, but the behavior is very
different in each other.
If called from client side, the |settings_payload| must be the
value sent in HTTP2-Settings header field and must be decoded
by base64url decoder. The |settings_payload| is unpacked and its
setting values will be submitted using submitSettings.
This means that the client application code does not need to submit
SETTINGS by itself. The stream with stream ID=1 is opened and the
|stream_user_data| is used for its stream_user_data. The opened
stream becomes half-closed (local) state.
If called from server side, the |settings_payload| must be the
value received in HTTP2-Settings header field and must be
decoded by base64url decoder. It is treated as if the SETTINGS
frame with that payload is received. Thus, callback functions for
the reception of SETTINGS frame will be invoked. The stream with
stream ID=1 is opened. The |stream_user_data| is ignored. The
opened stream becomes half-closed (remote).
This function returns 0 if it succeeds, or one of the following
negative error codes:
