We sometimes still could profit more from the sstate cache by avoiding
needless dependencies or shrinking artifact sizes.

To help identify cases where we trash the cache, we add two helper commands:

- isar-sstate show: list all artifacts of a PN
- isar-sstate delta: compare an artifact with others

The helpers work both with local and remote caches.

Best regards,
