Release ports acquired when checking available
Fixes issue
[BROOKLYN-130](https://issues.apache.org/jira/browse/BROOKLYN-130). Ensures
that the setReuseAddress is called before the port is bound. Removes the
attempt to connect to the port before binding it as unnecessary. Corrected off
by one error in loop so that port is not incremented beyond MAX_PORT_NUMBER.

Bind the socket after setting SO_REUSEADDR to true, behaviour is undefined

Ensure that the datagram socket is created in an unbound state

Removed unnecessary double checking of free port
commit f673e19910eaf160b2ba1c93e0d6a0d23a265f27

Fixed off by one error. After MAX_PORT_NUMBER comparison port is
incremented and checked. If not in valid range isPortAvailable throws an
exception which is less descriptive than the one in nextAvailablePort.

> The port 40127 is being returned by
> LocalhostMachineProvisioningLocation.obtainPort(..) which calls through
> several layers to Networking.isPortAvailable(..). This checks if the port is
> free but appears not to release the port. This appears to be related to
> socket.setReuseAddress(..) being called after binding the socket. The
> documentation requires it to be called before.
> Also an off by one error in Networking.nextAvailablePort(). The last value it
> passes to Networking.isPortAvailable(..) is MAX_PORT_NUMBER + 1.
