This patch allows to use lwIP as the implementation of the usocket module, instead of the existing socket-multiplexer that delegates the entire TCP/IP layer to the NIC itself. This is disabled by default, and enabled by defining MICROPY_PY_LWIP to 1. When enabled, the lwIP TCP/IP stack will be included in the build with default settings for memory usage and performance (see lwip_inc/lwipopts.h). It is then up to a particular NIC to register itself with lwIP using the standard lwIP netif API.
