OSC: Don't do reverse name lookup when handling packets

[perryprog]

I ran into an issue when using a listener/handler with the osc-server. Turns out, due to my being on a non-internet connected network, INetAddress was trying to perform a reverse name lookup on the server that had sent me the OSC packet. This was then hanging until the timeout was reached.

Using #getHostString will not perform a lookup, and instead just use the hostname/ip the address was initialized with.

I realize that this isn't (technically) a backwards compatible change, so let me know if I should add a flag to choose between the types of behavior.

What's the error you're getting, looks like you have some disfunctional /etc/hosts, would

(or (.getHostName src) (.getHostString src))

work to solve your problem?

I wasn’t getting any error (although I’m not sure if something would come up with some logging). .getHostName is still returning the IP address as the fallback, so your proposed alternative would not work.

Ok, since Overtone is already pre Java7 incompatible for other resons, I don't see a reson not to merge this.

https://docs.oracle.com/javase/7/docs/api/java/net/InetSocketAddress.html#getHostString()

This is basically getting the hostname or falling back to a string of the hostname, as you mentioend.

Thanks for this! Keep 'em coming, was on ICLC so I wasn't available for reviewing until today :)
