- 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.
