Lets remove unneded vlans from protocol interfaces

[spiccinini]

The scenarios we are using in the networks doesn't need vlans for the protocols. Let's remove them to reduce complexity and bugs (like #580 )

(I added the release-blocker label as this is a non-retrocompatible change, it has to be sorted out before next release)

I agree in removing not neded vlans!

It also would solve the problem with mediatek hardware switches

So, not needed VLANs are Babeld, BMX*, OLSR* ones, right?
But we would keep the BATMAN-adv one (if I remember correctly, @G10h4ck said that Batman needs to be on an interface by its own, and we use the VLAN=%N1 for breaking the Batman domains in different areas of the networks), right?

Yes. We can start with babel protocol and see how it goes.

But we would keep the BATMAN-adv one (if I remember correctly, @G10h4ck said that Batman needs to be on an interface by its own, and we use the VLAN=%N1 for breaking the Batman domains in different areas of the networks), right?

Yes. that's right

vlan=0 can be used to disable the vlan. I added some fixes for this use in #593
