The websocket stream is optimized to contain a small circular static buffer, reducing the number of I/O calls when reading data. The size of the buffer is tuned for maximum performance with TCP/IP and no long needs configuration: * read_some replaces read_frame * write_some replaces write_Frame * async_read_some replaces async_read_frame * async_write_some replaces async_write_frame * websocket::stream::read_buffer_size is removed Actions Required: * Remove calls websocket::stream::read_buffer_size * Use read_some and write_some instead of read_frame and write_frame
