Protect static global access with a global flag.

  - The global objects are protected by a global flag, during
    application teardown.
  - The following APIs, which could potentially be called during
    application teardown, will be NO-OP if global objects are no
    longer alive.
        rsContextCreate
        rsContextCreateGL
        rsContextDestroy
   - Added a test of the problematic use-cases.
