QUIC: create streams for STREAM_DATA_BLOCKED and MAX_STREAM_DATA. Creating client-initiated streams is moved from ngx_quic_handle_stream_frame() to a separate function ngx_quic_create_client_stream(). This function is responsible for creating streams with lower ids as well. Also, simplified and fixed initial data buffering in ngx_quic_handle_stream_frame(). It is now done before calling the initial handler as the handler can destroy the stream.
