c10d97484a Add more license tags with SPDX identifiers 
Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.

I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.

However, I can not garantee that I always picked the correct information
and/or did not miss license information.

8691d75917 odhcp6c: add route-workaround for broken IPv6-ISPs 
Some ISP seem to only do stateful DHCPv6 and not sending RAs.
This is technically broken because plain DHCPv6 doesn't carry routes.

We work around here by faking a default route to the DHCPv6 server
if we do not receive a useful RA from the ISP.

This workaround can be turned off with: option fakeroutes 0
