- inbv.c now only contains the Inbv-specific API and nothing else. - It will make easier for people to write their own boot themes & animations, by just copying/adapting the bootanim.c file (and the resources). - Add SAL annotations. - All INBV progress bar functions (except for InbvIndicateProgress()) should not be INIT-only functions, since they can be (not yet in ROS) used at later times -- namely, for feedback during hibernation.
