this looks like a good cleanup!

It's partly my fault that these format methods ended up a bit messy. I
exposed some of the internal to optimize UUID and, IIRC, a few other
internal APIs, then compact strings made all but the UUID optimization
redundant, which was moved into Long.java (see JDK-8148936) to narrow
down the API surface. All in all it's good to see this cleaned up and
improved further.

Thanks!
