boards.txt comes from #3722
lwIP sources are cloned from their origin, currently v2.0.3stable

I'm now very confused with all the lwips flying around. Is there any way to extract the version info from the lib? Something like a #define, or version string, or git commit, or whatever, that can get printed out? I don't trust what I'm building or linking against anymore.

Worst case md5 is simple

#ifndef LWIP_HASH_STR
#define LWIP_HASH_STR "esp1.4"
#endif
printf("lwIP-%d.%d.%d(%s)",
        LWIP_VERSION_MAJOR, 
        LWIP_VERSION_MINOR,
        LWIP_VERSION_REVISION,
        LWIP_HASH_STR);

LWIP_HASH_STR is not defined with lwip1.4

With lwip2, it says: lwIP-2.0.3(92f23d6(tag:STABLE-2_0_3_RELEASE)).
The hash number is the lwip commit ref, with the tag if there's one.

The two previous PR are now closed.

@devyte @davisonja LWIP_VERSION_MAJOR is accessible in sketch with #include "lwip/init.h".
It was already the case with lwip1.4. What do you think should be further done about that ?
@igrr @devyte @davisonja are you OK with the included boards.txt ?
I have only tested Generic/nodemcu(ESP01), wemos D1R1, D1-mini and D1-mini-lite(with esp8285).

boards.txt looks good, but i'll check with nodemcu. Will report back.

Be aware that the ESPAsync libs don't seem to build with lwip2.
@me-no-dev at first glance, the changes needed seem minimal, but I didn't go through them in detail.

@me-no-dev changes probably will be similar as #3129.

@me-no-dev ESPAsyncTCP builds now. Will you also update ESPAsyncUDP? That would allow me to build my application and start testing :)

ESP8266LLMNR lib doesn't seem to build due to differences in UdpContext signatures

@devyte - ESPAsyncUDP also updated, works for me with LWIPv2
