This patch refactors imagebin element creation and linking into separate functions, and adds re-using also for imagebin internally created elements. So this refactoring allows creating imagebin elements already in NULL state when application sets the image mode, and next state change from NULL to READY will be faster. This reduces first capture latency. Earlier the elements were both created and linked in NULL to READY state change.
