If the server URI contains an IPv6 address, e.g.
"tcp://[2002:3e92:dead:beef:250:56ff:fe28:1234]:1883" (invalidated address in example)
then MQTTAsync_create fails with return value -2 on Windows machines.

If you use the same valid serverURI on a Linux machine, for example within test/test4.c, then the test passes.

Partial fix for bug 484496

With this fix MQTTAsync_Create does not fail with -2 any more.
But there are other issues, which prevent MQTT and IPv6 from working on Windows.

Patch to remove the leading '[' from IPv6 addresses

With this 2nd patch the socket could be created.
But connecting to a broker with IPv6 address still fails.

I've added a fix to the fixes branch. As well as the persistence directory name, the socket initialization for IPv6 was not correct.

Merged to develop.
