Jack Whitham 8a3c9f0bf2 extmod/modlwip: Call user callback on newly-received UDP or RAW packet. 
User callbacks allow code to respond to incoming messages without blocking
or polling.  User callbacks are optional, and if no callback is registered
the code has no effect.

The mechanism is the same as for TCP: when a connection is accepted or a
TCP packet is received, a user callback is executed.

Fixes issue #3594.
