include the scope-id when binding an IPv6 socket, as required for IPv6 link-local addresses. Not doing this would make the OS reject the bind and throw an exception, disconnecting the client.

This looks convoluted. I am not sure when I will have the resources to look at this. I feel like this belongs to ioloop.py file, and a is_local_ipv6() helper function would make things clearer, but I can't say more than this for now. IPv6 is hard. |

this should fix #664, where clients would get rejected if they connected from a link-local IPv6-address (
fe80:throughfebf:). I'm not sure if this is the optimal way to fix this, but I believe it is at least sound :-)I didn't add a test for this, since I think it would require an IPv6 link-local address to connect from, and I'm not sure how to assign one without running the test as root.
The tests did not seem any worse for the wear on either Windows, Linux, or Macos -- on Linux I did have to replace
net_connectionswithconnectionsinpyftpdlib/test/*.pyand on Macos there was a small number of seemingly unrelated issues; pyftpdlib-test-macos.txt
