Cannot run collocated tests with IPv6

[pepone]

When using IPv6 collocated test doesn't work. The issue is that the proxy endpoint doesn't match the published endpoint

The reference uses the 0:0:0:0:0:0:0:1 from the default host set by the scripts, and the published endpoint uses ::1

This affects C++ and C#, Java works fine with 0:0:0:0:0:0:0:1

I think we have to update collocated test to set PublishedHost to the value returned by the test helper getTestHost. This is always the same as Ice.Default.Host.

[bernardnormier]

Not sure that's the correct fix. It sounds like a bug in the hostname/address comparison performed by isLocal.

[bernardnormier]

It's not immediately clear why it works in Java but not C++ and C#. The logic appears identical in all 3 languages. They rely on IPEndpointI.equivalent, that as far as I can tell, makes a straight string comparison for the host. So it shouldn't work in Java either.

[bernardnormier]

Another possible solution: fix the test scripts to be consistent, and use ::1 everywhere.

Why are we using ::1 for non-colloc and 0:0:0:0:0:0:0:1 for colloc?

[pepone]

In C++ and C# expandHost returns ::1 for 0:0:0:0:0:0:0:1

[bernardnormier]

#3161 was not a complete fix.

We still need to:

• run at least one test with ipv6 and colloc (when running the tests with --all)
• fix C++ and C# (and possibly JS) to implement IPEndpoint::equivalent with "normalized" IPv6 addresses
