Add a public @hide InetAddress.isNumeric.

Some frameworks/base callers want to know whether they can call
getAllByName/getByName without incurring a DNS lookup. Rather than have them
write their own JNI to do the AI_NUMERICHOST getaddrinfo(3) call, let's just
offer them ours.

Why don't I fully expose getaddrinfo(3)? Because it doesn't map to Java API
very well, and no-one needs that yet. So for now, let's take the easy way out.

Also improve some misleading javadoc.
