This set fixes a memory lifetime issue which in the end happens because the
camera manager needs to outlive all of its object, including the
FrameBufferAllocator. This is fixing a crash reported at:

https://bugs.libcamera.org/show_bug.cgi?id=211

Nicolas Dufresne (3):
  gstreamer: allocator: Ensure camera manager stay alive
  test: gstreamer: Simplify single stream test
  test: gstreamer: Test memory lifetime
