Minor additions to nio/Buffers, util/IntIntHashMap and os/NativeLibrary

Buffers add 'float[] getFloatArray(double[])' conversion,
ready to replace all JOGL InternalBufferUtil's.

NativeLibrary/DynamicLinker add global lookup method
allowing Unices and OSX to lookup a symbol globally.
However, this is not recommended, due to the lookup costs.
Windows is not supported here.

Primitive type HashMap's (IntIntHashMap): Added putAll()
