Refactored platform extensions out of the GL interface and

implementation and into their own objects according to the JSR-231
expert group's resolutions. Moved the interfaces declaring these
extensions into the platform-specific implementation directories and
added a loosely-specified GL.getPlatformGLExtensions(). This will
shrink the size of the platform-independent jar file considerably as
the implementing class for the public GL interface is now no longer
replicated for each platform. The build process is also simplified a
fair bit; more simplifications are possible.
