[0/9] batman-adv: License cleanup

Hi,

the kernel community is currently trying to make the licensing status more
clear in each file. This is mostly done by adding SPDX license identifiers
and defining a set of rules how these license related information has to
be stored.

I've used this opportunity to go through all files (for example with FSFE's
`reuse lint`) and to annotate the files according to the "Linux licensing
rules" and FSFE's REUSE practices.

There are two things which could be seen as controversial:

* change of batman_adv.h to the Linux preferred license
  (I am waiting for Acks)
* explicitly mark remaining files as licensed under the GPL-2.0

Kind regards,
	Sven
