[chore] Improve copyright header handling (#1608)
* [chore] Remove years from all license headers

Years or year ranges aren't required in license headers. Many projects
have removed them in recent years and it avoids a bit of yearly toil.

In many cases our copyright claim was also a bit dodgy since we added
the 2021-2023 header to files created after 2021 but you can't claim
copyright into the past that way.

* [chore] Add license header check

This ensures a license header is always added to any new file. This
avoids maintainers/reviewers needing to remember to check for and ask
for it in case a contribution doesn't include it.

* [chore] Add missing license headers

* [chore] Further updates to license header

* Use the more common // indentend comment format
* Remove the hack we had for the linter now that we use the // format
* Add SPDX license identifier

Additional IP range validations (#1152)
* [bugfix] Ensure requests happen over TCP

It's possible for the network to be udp4 or udp6. This is rather
unlikely to occur, but since we're given the network anyway as part of
the Sanitize function getting called we might as well check for it.

* [chore] Align reserved v6 blocks to IANA registry

* [chore] Add test for ValidateIP

The net and netip packages diverge in that net.ParseIP will consider an
IPv4-mapped address to be an IPv4 address and as such it would get
caught by the IPv4Reserved list. However, netip considers it an IPv6
address, so we need to ensure the mapped range is in IPv6Reserved.

* [chore] Align reserved v4 blocks to IANA registry

This includes a number of tests for /32's explicitly called out in the
registry to ensure we always consider those invalid.
