Scrap v3.2 release cycle and move to v4.0 directly

Planned changes will directly change the behavior of conditions, and
instead of having to implement compatibility wrappers and further
complicate the code, we've taken the decision to go for v4 directly.
This allows us to also rip out the complex inetd support.

Other changes in this commit:

- Revert back to .tar.gz distribution archives, by popular demand
- Add .sha256 checksum for .tar.gz archive
