JOGL Error Handling

- Catch invalid drawable for all impl. at GLContextImpl if !created yet

- GLDrawableFactoryImpl (X11/WGL) catch and fwd Throwable properly

- GLProfile catch LinkageError and handle it

In case of nothing is available, a final ExceptionInInitializer will be thrown,
with the produced GLException that no GLProfile is available.
