I finally had a first look at it and played around a little bit.

How do you want to review patches for this? Pull requests on the github
repo or patches send on the linux-wpan list?

So far just some basic stuff I stumbled over when playing with it. Build
fixes (SCOPE_ID and different lua pkgconfig namings), leak fixes to
config.c as well as a travis setup to get building on CI as well as
submitting to Coverity scan service (the later two are already tested in
practice with some dev branches I pushed to the github repo, hope you
don't mind).
