Bug 1150 - Fix GLContextImpl.createImpl(..) NoARBCreateContext and '!ARB GL >= 3.1' issues

This fix solves the described issues below.

Test cases added for onscreen and offscreen drawables,
the latter includes Window's bitmap special case.

GLContextImpl.createImpl(..): Fix NoARBCreateContext and '!ARB GL >= 3.1' issues:
=================================================================================
GLContextImpl.createImpl(..) implementation of X11GLXContext and WindowsWGLContext
wrongly handles the case of NoARBCreateContext.
Here the !ARB created context shall allow GL >= 3.1,
since ARB context creation is disabled and 'no mix' can occur.

The latter was already intended due to failure criteris 'createContextARBTried'
in:
  if( glCaps.getGLProfile().isGL3() && createContextARBTried ) {
     failure("createImpl ctx !ARB but ARB is used, profile > GL2 requested");
  }

Further, WindowsWGLContext treats glCaps.isBitmap()
within the 'createContextARBTried=true' case, but it shall never
tried using the ARB context creation method.
This even lead to the issue of creating a 1.1 context,
but having the ProcAddressTable being still on the GL > 2 cached table.
This is due to 'setGLFunctionAvailability(..)'.

Ensure 'setGLFunctionAvailability(..)' is functional
====================================================

Caller shall either throws an exception if method returns false
or issues a state reset.

In case 'setGLFunctionAvailability(..)' throws an exception itself,
the states are no issue.
