Added code to the windows port to test this: see PCAPIF_RX_READONLY and PCAPIF_RX_REF.

Updated summary: IPv4 reassembly writes into the rx buffer, too.

Since supporting readonly RX is possibly slower and uses more memory, this should probably be an option...

tcp writes into rx pbufs (at least network byte order flips). Let's try to change this. I don't know if it works at all (regarding ooseq, especially) -> low prio
