RFR: 8365239: Spec Clarification - InterfaceAddress:getBroadcast() returning null for loop back address

[Daniel Fuchs]

Hi,

This is a documentation change only. The specification of  `InterfaceAddress:getBroadcast()` should not say anything specific about the loopback interface as it appears that on some systems a broadcast address can be configured on the loopback. The API documentation of `InterfaceAddress:getBroadcast()` is updated to simply say that:

     * Some network interfaces do not support broadcasting and may
     * also return {@code null}.
