Add SPDX-License-Identifier lines to several source files under the network sub-directory. Work on files in the core, dns_resolver, ipv4, ipv6 and netfilter sub-dirs. Remove boilerplate and license reference text to avoid ambiguity. Rusty Russell has expressed that his contributions were intended to be GPL-2.0-or-later.
