Fix T39928: Blender crash/freeze when game engine is started with animation played directly on camera object with parents.

Updating object IPOs is not currently thread-safe since it also updates
children. This leads to problems when parents and children are both
animated. For now, updating object IPOs is done in its own loop to avoid
threading issues.
