Let's expose local VMs/containers under ._dhcp by default. Let's also
expose WIFI AP clients under .home.arpa (i.e. the RFC8375 domain for
home networks).
Arguably, CC0 is just fine for examples since they are not code. But it's
easier to be consistent and just use MIT-0 for all "documentation". Thus,
the license is changed similarly code examples under man/.
Based on 'git shortlog -ns network/*' and 'git log -p', the following folks
should ack this:
Zbigniew Jędrzejewski-Szmek
Lennart Poettering
Tom Gundersen
Yu Watanabe
Daan De Meyer
Marc-André Lureau
This matches what we have for example programs under man/, and is nice
because it allows people to copy the files as they wish without worrying
about copyright. The files are too trivial to copyright anyway.
I think 80-wifi-adhoc.network is safe enough, since it just enables
the link-local addressing. But the other two enable DHCP in client
or server modes, and we should not do this by default.
