Details:
(As you probably all know:) netbuf_copy_partial() copies TCP data from a pbuf
into the buffer provided by an application using the netbuf- or socket layer.
This function seems to be a bottle neck since it uses 2 loops and copies byte
per byte.
My implementation uses memcpy(), which is much faster than byte copy (if the
payload is aligned!!!)!
[If the payload or dataptr is not aligned, we gain nothing :( ]
