Cleanup nio package, class names and code (of recently added code)

- org.jau.nio.NioUtils -> org.jau.nio.NativeIO
  - Avoid clash with org.jau.lang.NioUtil
  - Hint package abbreviation 'nio' -> 'Native IO'

- org.jau.sys.JauUtils -> org.jau.io.PrintUtil and spread a few functions to
                          -> org.jau.nio.NativeIO
                          -> org.jau.util.BasicTypes
