In c357ea1, we switched from making an IPv4 connection, to an IPv6 one. This fixed some nasty lag on Windows, but it turns out that it also broke IPv4-only environments completely. So now we fall back to opening a v4 connection if the v6 connection fails.

Hmm, Windows CI is telling me I definitely messed something up. |
The previous commit was failing on Windows. Maybe we can't call `local_endpoint()` before `bind()`?

Got confirmation from the original reporter that this is fixing the Catalogue in their IPv4-only environment. Would be good to get this into a release... |

LGTM. It's not increasing the time to run GafferSceneTest.CatalogueTest.testYouOnlySaveOnce at all in my testing.

@ericmehl, if you could check that the lag is still banished on Windows, that would be great. I think it should be fine because we open the v6 connection first still, but I'm a bit out of my comfort zone with this, so the more testing the better.
