scripts for comparing core closed libs against esp-nonos-sdk ones

No description provided.

[d-a-v]

Currently, the output of this script gives:

$ ./sdk-compare-libs ~/dev/esp8266/ESP8266_NONOS_SDK

nonos-sdk                 = '.../esp8266/ESP8266_NONOS_SDK'
core root directory       = '.../esp8266/esp8266'
temporary nonos-sdk clone = '.../esp8266/esp8266/tools/sdk/lib/compare/NONOSDK.deleteme'

If libmain.a is not found, it should be the one around the same libpp.a's commit

I think this could be really useful, but it feels somehow not quite complete. The current output of e.g.: the include compare script shows every difference, and I think that includes our own patches. Therefore, looking at the output is rather confusing.
Maybe our own patches should be factored out somehow, so that the output is cleaner and shows only the differences introduced in the new SDK?
To be clear, I'm ok with merging as is, it can at least serve as a first step.
