Hash calculation of an image can be a time consuming operation, with the
possibility of making the hardware watchdog (if present/enabled) expire in the
middle. Add watchdog-aware hash calculation functions and make image hash
calculation use them.

Bartlomiej Sieka (2):
      Use watchdog-aware functions when calculating hashes of images
      Add support for calulacting hashes with watchdog triggering
