Subject: Add com.jogamp.common.util.PrimitiveStack (FloatStack and
 IntegerStack), a simple primitive stack implementation.

Currently only FILO put/get operations are implemented using either
primitive arrays as I/O itself or <Type>Buffer.

Unit tests are included..

Note: Only FloatStack is implemented in a manual, where others (IntegerStack)
      is derived (generated) from it. Same goes w/ unit tests.
