Misc Rename/Reloc; GLArrayData*/PMVMatrix enhancments; Test fixes/adds (GearsES1/ES2)

rename/reloc:
 - javax.media.nativewindow.util:
      DimensionReadOnly -> DimensionImmutable
      PointReadOnly -> PointImmutable
      RectangleReadOnly -> RectangleImmutable

   unified 'immutable' name as used within jogamp already

 - remove array handler from public API
   com.jogamp.opengl.util.GL*ArrayHandler -> jogamp.opengl.util.GL*ArrayHandler

 - GLArrayData: Clarify method names
     getComponentNumber() -> getComponentCount()
     getComponentSize() -> getComponentSizeInBytes()
     getElementNumber() -> getElementCount()
     getByteSize() -> getSizeInBytes()

- FixedFuncPipeline: Moved def. array names to GLPointerFuncUtil

enhancement:
  - GLArrayDataServer: Add support for interleaved arrays/VBO
  - GLArrayData*.createFixed(..) remove 'name' argument (non sense for fixed function)
  - PMVMatrix:
    - one nio buffer
    - removed 'Pmv' multiplied matrix
    - removed 2x2 cut down 'Mvi' normal matrix (use 4x4 Mvi)
    -
tests:
 - RedSquare -> RedSquareES1/RedSquareES2
 - Gears ES1 fixed + ES2 added. Both work properly and share common Gears VBO construction
 - Added TestMapBuffer01NEWT, testing glMapBuffer
