Fix EGLDrawableFactory ES1/ES2 detection for !pbuffer ; Misc robustness changes for GLDrawableFactory ..

- EGLDrawableFactory ES1/ES2 detection for !pbuffer
   - isEGLContextAvailable(..) -> mapAvailableEGLESConfig(..)
   - handle case where no pbuffer configuration is available (nokia n9 meego ..).
     in such case, assume availability if onscreen profile is avail.

- EGLDrawableFactory.getOrCreateEGLSharedResource(..)
   - avoid double creation attempt (similar to SharedResourceRunner)

- EGLGraphicsConfiguration.EGLConfig2Capabilities(..) respect EGL.EGL_CONFIG_CAVEAT's EGL.EGL_SLOW_CONFIG
   - if EGL.EGL_SLOW_CONFIG -> no hw accel.

- Fix GLContext.getRequestMajorAndCompat(..): Proper handling of ES1 and ES2

- Add abstract GLDrawableFactory.isComplete(): Only if true use the factory for 'getFactory(..)' avoid using incomplete ones.
