Follow-up Comment #9:

I've implemented the idea from comment #8, but throught a flag in conn->flags
rather than an additional argument to netconn_recv():

- the socket code now calls netconn_set_noautorecved(conn, 1) after creating
a connection,
- this lets netconn_recv skip the do_recv part,
- the socket code calls netconn_recved() before it returns from lwip_recvfrom
with off > 0

This is right now not integrated with close/shutdown (as mentioned in comment
#4), but I see that as a different problem. It might be solved by changing the
netconn_recved() implementation, but it might also be solved differently...
