Mechanism to detect changed runtime images at boot

This patch adds a mechanism to detect if the current runtime image is
the same as during the last run.

This mechanism consist of several parts:
1. Reliable 'fingerprint' for an image
2. Safe way to store the image fingerprint
3. A helper to detect image changes and trigger a hook
