src: Add GPLv2+ header to .c files of recent creation

This patch comes after a proposal of mine at NFWS 2022 that resulted in
agreement to license recent .c files under GPLv2+ by the attendees at this
meeting:

- Stefano Brivio
- Fernando F. Mancera
- Phil Sutter
- Jozsef Kadlecsik
- Florian Westphal
- Laura Garcia
- Arturo Borrero
- Pablo Neira

It has already happened that one of the external library dependencies
was moved to GPLv3+ (libreadline), resulting in a change to libedit by
default in b4dded0ca78d ("configure: default to libedit for cli").

I have added the GPLv2+ header to the following files:

Eric Leblond and Elise Lennion did not attend NFWS 2022, but they
acknowledged this license update already in the past when I proposed
this to them in private emails.

Update COPYING file too to refer that we are now moving towards GPLv2 or
any later.
