…format also dmverity.Format will simply return the root hash instead of the old Info struct since the new design doesn't have a need for a separate header.
adding helpers for retrieving and parsing a dm-verity superblock from a dm-verity hash device/file. This will be first consumed by the snap integrity API which will need to detect the salt that was used for the dm-verity data generation. Moreover callers to dmverity.Format will need to have a way to retrieve the parameters used by veritysetup if no parameters are passed (and veritysetup chooses default values).
the new design simplifies how snap dm-verity data for a corresponding snap are generated and used by having them as a separate file (i.e located next to the snap file) instead of attaching them at the end of their snap file by default. The extra integrity data header is removed as all the information needed to mount a snap with its verity data (root hash, salt, other parameters) will be retrieved from a new integrity stanza in snap-revision assertions.
