lwIP has already used its own log level when deciding what to print.
If we reach the LWIP_PLATFORM_DIAG message no further filtering should
happen, so set the log level to match the macro used.
This fixes the missing IP addresses from ifconfig. Before:
> ifconfig
Iface ET0 HWaddr: 24:0a:c4:e6:0e:9f Link: up State: up
Link type: wired
inet addr: mask: gw:
inet6 addr: scope: link state: valid preferred
inet6 addr: scope: global state: valid preferred
Iface ET1 HWaddr: 24:0a:c4:e6:0e:9c Link: up State: up
Link type: wireless
inet addr: mask: gw:
inet6 addr: scope: link state: valid preferred
inet6 addr: scope: global state: valid preferred
>
With this change:
> ifconfig
Iface ET0 HWaddr: 24:0a:c4:e6:0e:9f Link: up State: up
Link type: wired
inet addr: 10.4.4.81 mask: 255.255.254.0 gw: 10.4.4.1
inet6 addr: fe80:0:0:0:260a:c4ff:fee6:e9f scope: link state: valid preferred

- most were trivial
- missing group close or open
- extra space
- no doxygen comment
- name commad might open an implicit group
this hould also be implicit cosed but does not happen somtimes
- crazy: internal declared groups have to be closed internal
If DEVELHELP is not set `LOCK_TCPIP_CORE()`/`UNLOCK_TCPIP_CORE()`
are not defined, leading to a build failure.
Defining them to no-op leads to a run-time segmentation fault, so
better always use those functions.
Lists state, link type, v4/v6 addresses.
Currently read-only.
Using lwIP debug system to print addresses, to limit dependencies
and work with dual stack setup. Most other code seems to only
allow either v4 or v6 networking. For that to compile I
had to change the `SZT_F` format string due to this error:
```
error: format '%lu' expects argument of type 'long unsigned int',
but argument 2 has type 'size_t {aka unsigned int}'
```
Switching to the lwIP default format string here.
Outputs the following on my ESP32 board with Ethernet,
when both v4 and v6 are enabled in examples/paho-mqtt:
```

If module log is used, log.h should be included. Otherwise, it might lead to compilation problems since LOG_ERROR macro isn't know in expansion of LWIP_PLATFORM_ASSERT macro.
