Relax Bug 613 workaround of commit 92398025abdabb2fdef0d78edd41e730991a6f94

Utilizing a GlobalToolkitLock in general to lock the display connection results in deadlock
situations where locked surfaces signal other [offscreen] surfaces to render.

We have to see whether we find a better solution, for now sporadic XCB assertion still happen.
But it is preferrable to point to the root cause, then to jumping through hoops to complicate locking
or even to deadlock.

Locking:
  - X11GLXGraphicsConfigurationFactory add missing device locking in:
    - getAvailableCapabilities
    - chooseGraphicsConfigurationStatic

  - Newt/X11Window: Discard display events after window close.

Relax ATI XCB/threading bug workaround:
  - ToolkitProperties: requiresGlobalToolkitLock() -> hasThreadingIssues()
  - NativeWindowFactory: Don't use GlobalToolkitLock in case of 'threadingIssues' the impact is too severe (see above)
  - NativeWindowFactory: Add getGlobalToolkitLockIfRequired(): To be used for small code blocks.
                         If having 'threadingIssues' a GlobalToolkitLock is returned, otherwise NullToolkitLock.
  - X11GLXContext: [create/destroy]ContextARBImpl: Use 'NativeWindowFactory.getGlobalToolkitLockIfRequired()' for extra locking

Misc Cleanup:
  - *DrawableFactory createMutableSurface: Also create new device if type is not suitable
  - *DrawableFactory createDummySurfaceImpl: Pass chosenCaps and use it (preserves orig. requested user caps)
