Refactorings to support building JOGL for OpenGL ES 1 and OpenGL ES 2.

"ant -Djogl.es1=1" builds JOGL for OpenGL ES 1.
"ant -Djogl.es2=1" builds JOGL for OpenGL ES 2.
"ant" builds JOGL for desktop OpenGL (2.1).
Building desktop OpenGL is currently broken (FIXME) -- more
refactorings are necessary.
When compiling, it is currently necessary to specify
-Djogl.noglnatives=1 on the ant command line as well, because the
generated native code does not link properly since we do not have
OpenGL ES libraries on the desktop. Building the generated native code
using a cross-compiler is not yet hooked up into the ant build
mechanism. It is necessary to build the generated native code with
external tools.
Also incorporated spatialized audio framework using Windows waveOut
device; this is a temporary measure until a different workspace can be
found for this code.
