See #731 and r14274 + r14275.

IPv6 tracker ticket: #1594

netifaces can give us the ipv6 mask and we should resolve the hostname and match that.

• r16893 fixes the avahi publisher when using ipv6 addresses
• r16895 fixes a server start failure on macos with ipv6 addresses
• r16896 handles ipv6 addresses better
• r16897 parses interface numbers on win32

All should be backported.
With these changes, the avahi mdns publisher does show the correct ipv6 address, but the pybonjour published (used on win32 and macos) does not.
For macos, we could move to zeroconf (#1644).

This will do for now.
