Fix bug 564 - part 2 (X11 Mesa 8.0.1 GL 3.0 w/ failing GLX_ARB_create_context)

Tolerate a buggy ARB createContext impl (always failing to create a context).

Now we only reset the GLContext state and
set the context/device availability flag if ARB create context actually was successful.
Otherwise the fallback 'old' context is being used w/o having it's context state cleared
and context/device availability is set later on.

This makes the general use of ARB_create_context more stable.

Minor changes:

- Non compatibility fallback: Try forward context instead.
- Limit ARB context 'seeking' to >= OpenGL 2.0
