QPID-4931: Remove removed member function from windows SocketAddress
code too. While there bring this code up to date with other recent
changes to the POSIX equivalent code.
> Broker should only listen to a single network address if "--port 0" is

> Key: QPID-4931
> URL: https://issues.apache.org/jira/browse/QPID-4931
> Project: Qpid
> Issue Type: Improvement
> Components: C++ Broker
> Reporter: Andrew Stitcher
> Assignee: Andrew Stitcher
> Fix For: 0.23
>
>
> The C++ broker has a setting which is really only useful for testing which
> allows the broker to listen to whichever port the kernel gives it. In this
> mode it prints the received port on stdout for subsequent testing programs to
> use.
> When you listen to multiple network addresses (addresses are multiple network
> interfaces or multiple protocols on the same network interface - IPv4 & IPv6
> for example) the broker has to remember the port it got for the first address
> and then try to get the same port for subsequent addresses.
> Unfortunately there is no guarantee that the same port will actually be
> available on the other addresses so the entire broker startup can fail.
> In the testing environment which this is useful for you only care about the
> IPv4 loopback address in any case so we have to ensure that this address is
> the only (or at least the first) address used.
> Because we can't guarantee getting the same port for more than one address it
> makes sense to restrict "--port 0" to only listening to a single address.
> I propose that if the broker detects that more than one address has been
> specified or is implied by the network setup it should list to the first
> address and log a warning message with the actual address listened to.
