5085,Accept IPv6 address literals (with embedded scope ids) in IReactorTCP.connectTCP,exarkun,glyph,"Similarly to #5084, Twisted should provide low-level support for [wiki:IPv6] TCP clients.  `IReactorTCP.connectTCP` implementations should accept IPv6 address literals and attempt to establish a connection to that IPv6 address.

All of the IPv4 features of `connectTCP` will remain the same.  Passing an IPv4 address literal or a hostname will still attempt a connection to an IPv4 address.

The `IConnector` returned will return an `IPv6Address` (see #5084) from its `getDestination` method.

When a connection attempt is successful, the factory's `buildProtocol` method will be invoked with an `IPv6Address` instance giving the server's address.

The protocol will be connected to an `ITCPTransport` implementation which also returns `IPv6Address` instances from its `getHost` and `getPeer` implementations.

Once this is resolved, Twisted clients should be able to establish outgoing TCP connections to IPv6 addresses, eg `::1` or `fe80::1%lo0` or `2001:6b0:e:2018::172%en3`. Note that where the platform requires the scope id, `connectTCP` will require the scope id.
