On the road to 3.0.17.4
This reverts all changes since 3.0.17.3 but the UPnP fix (!1598 (merged)) and bump the configure.ac version
This is the best compromise I can come up with to:
- Ensure we don't bump anything that's not required for 3.0.17
- Fix the UPNP regression
- Still bumps the version in configure.ac
that doesn't involve push forcing some commits in/out.
Opinion are most wanted
