[concurrency-interest] Constructors of AtomicXXX and AtomicXXXArray

I have not encountered a context where there is a need to initialize
an atomic "array" from an existing array. That's not to say it doesn't
exist, but there are no use cases that highlighted the need for it. Do
you have an actual use case for this?

new AtomicInteger(Integer.parseInt(theString, theRadix))
There's no need to burden a class with conversion facilities when the
conversions already exist (and in a fuller form) elsewhere.

String parsing typically has application specific error-handling
associated with it, so you're much better off doing the conversion
yourself. Just my opinion.
