Compatibility with versions prior to 2.8.12 is being deprecated,
resulting in build warning messages. The minimum for the official
supported distros is 3.7.2 (Stretch), so the version could be moved
forward when newer features are required.

The updates include:
- The ability to specify a custom gpodder service.
- Use https instead of http for gpodder.net.
- A fix that prevents encoded URLs from being re-encoded.
