Damien George 26e978e7bc extmod/modlwip: Implement a queue of incoming UDP/raw packets. 
The bare-metal lwIP socket interface is currently quite limited when used
for UDP streams, because it only allows one outstanding incoming UDP
packet.  If one UDP packet is waiting to be socket.recv'd and another one
comes along, then the second one is simply dropped.

This commit implements a queue for incoming UDP and raw packets.  The queue
depth is fixed at compile time, and is currently 4.

This allows better use of UDP connections, eg more efficient.  It also
makes DTLS work better which sometimes has a queue of UDP packets (eg
during the connection phase).
