UBI-utils: add compare feature
This is a new feature for pfiflash, called "--compare". It allows the user
to simulate a pfiflash session without actually changing the flash
content. If the flash content is equal to the data in the pfif file,
pfiflash returns zero. A positive value is returned when the flash
content differs from the pfi file, which indicates that an update is
necessary. This feature is useful when a controller mounts an NFS share
during boot and has to determine if a pfi file stored on this share
contains a code update. Modified PDD values are also registered by the
compare feature.
