picoTCP v1.7.0

It's been way too long in the making, but it's finally here : picoTCP v 1.7.0.
This is the first time the code is being released under both GPLv2 and GPLv3.
We've also improved the example code in the README.md, and clarified our use of a Contributors License Agreement.

Too many code changes to enumerate them all, but the most important changes are :

• 6LoWPAN support
• fixed many issues reported by coverity scan
• removed potential memory leaks (especially in case of failing mallocs, i.e. out-of-memory situations)
• many code quality improvements, internal refactorings
• limited hotplug detection support (currently only on SLAACv4)
• improved Bonjour conformance (not there yet, but getting closer)
• improvement in DNS response parsing
• various other bugfixes

for more, please run git log :-)
