Fix 'NIOOnly' impl ; Use 'final' in gen. Java stubs ;

- Fix 'NIOOnly' impl

- Use 'final' in gen. Java stubs ;

- No null check for Buffers.isDirect(arrayArg) [required]

- Clarify Buffer arg API doc (NIOOnly or NIODirectOnly)

- cleaned up loop / branch (CMethodBindingEmitter)

- remove unsued vars/code

- Tests:
  - covers normal/NIOOnly/NIODirectOnly
  - covers passing null for array and NIO
