OS mode (TCPIP thread)

Overview

Use this mode if you run an OS on your system. It is recommended to use an RTOS that correctly handles priority inversion and to use LWIP_TCPIP_CORE_LOCKING.
Porting: implement all functions in sys_layer.
You can use "raw" APIs together with tcpip_callback, and all Sequential-style APIs.
