Code was more or less copied into each backend, so it's better to
have a shared implementation.

Create robust egl context if possible


Verify that context is robust before resolving robust functions

The extensions specify that you are only allwoed to use the robust
functions if the context is robust. Given that we need to query
whether the robust is context and fall back to our workaround if
the context is not robust.
  • GLES is tested on Nexus 5: works (note mesa seems not to provide the extension)
  • OpenGL is tested with EGL on mesa
