Add int-based Ipv4Address{NoZone} methods to IetfInetUtil
Description
When Ipv4Addresses are interfaced with external systems through Netty it would be nice if we could treat them as plain 32bit ints, so that ByteBuf.writeInt() can be used instead of ByteBuf.writeBytes(). Add utility methods to allow this to happen.
