Subject: Add GLRendererQuirks; Fix shared EGL/ES resources;

Add GLRendererQuirks:
  - Contains centralized 'tagged' workarounds for GL renderer bugs (quirks)
  - Accessible via GLContext and GLDrawableFactory
  - Initialized in GLContext.setAvailability*
  -

Simplify GLGraphicsConfigurationUtil.fixOffscreenGLCapabilities(..) & use Quirks
  - use quirks
  - instead of passing booleans for each config, pass factory & device

Fix shared EGL/ES resources:
  - GLProfile needs to initialize EGLDrawableFactory's shared resources before desktop,
    so EGLDrawableFactory can use the fallback defaultDisplay & defaultSharedResource
    for host mapped sharedResources (hack).

  - If using defaultSharedResources for host mapped ones,
    do not go through initialization cycles - simply map (sharedResource + context).

  - EGLDrawableFactory: Use device's unique-key instead of connection only,
    since the latter causes a collision (EGL-connection == X11-connection).
