I was intending to make all the Netlink Spec code BSD-3-Clause
to ease the adoption but it appears that:
- I fumbled the uAPI and used "GPL WITH uAPI note" there
- it gives people pause as they expect GPL in the kernel
As suggested by Chuck re-license under dual. This gives us benefit
of full BSD freedom while fulfilling the broad "kernel is under GPL"
expectations.

I had a (bright?) idea of introducing the concept of enum-models
to account for all the weird ways families enumerate their messages.
I've never finished it because generating C code for each of them
is pretty daunting. But for languages which can use ID values directly
the support is simple enough, so clean this up a bit.
"unified" model is what I recommend going forward.
"directional" model is what ethtool uses.
"notify-split" is used by the proposed DPLL code, but we can just
make them use "unified", it hasn't been merged :)

Add schemas for Netlink spec files. As described in the docs
we have 4 "protocols" or compatibility levels, and each one
comes with its own schema, but the more general / legacy
schemas are superset of more modern ones: genetlink is
the smallest followed by genetlink-c and genetlink-legacy.
There is no schema for raw netlink, yet, I haven't found the time..
I don't know enough jsonschema to do inheritance or something
but the repetition is not too bad. I hope.
