add lwIP TCP/IP stack as a runtime driver, native socket syscalls, SysGetMemoryStatus replacing CatchAllDebugBucket, fix timeGetTime to return milliseconds, fix SysSleep to interpret argument as milliseconds, SysGetTick now returns microseconds, harden all syscalls against bad user pointers with CopyFromUser/CopyToUser/MmProbeUser throughout, add networking test apps, port-forward 8080 in runa.bat, split LWIP_DRIVER_CFLAGS, add settings.ini to deploy, remove ethernet.c stub
