* LWIP_ASSERT_CORE_LOCKED: Macro to check whether lwIP's threading/locking
* requirements are satisfied during current function call.
* This macro usually calls a function that is implemented in the OS-dependent
* sys layer and performs the following checks:
* - Not in ISR
* - If LWIP_TCPIP_CORE_LOCKING=1: TCPIP core lock is held
* - If LWIP_TCPIP_CORE_LOCKING=0: function is called from TCPIP thread
