This is the replacement for (rather nasty) criu show code. Also this is the way to edit the images before restoring from them.

=== On-the-fly conversion ===
There's an idea to make CRIU spawn CRIT and read images "through" it, to allow for at-the-restore-time modifications. For details, see https://github.com/xemul/criu/issues/59.
=== Convert between different image versions ===
Right now we store the images version in inventory.img and collect info about [[what's bad with V1 images]]. If some day we have v2, CRIT will convert from v1. And for backward compatibility we'll use on-the-fly conversion when restoring from old images.
=== Check/validate images ===

Check that
* all images are present

* the inter-images IDs are in consistent state
* the inter-images IDs are in consistent state
For details, see https://github.com/xemul/criu/issues/44.
=== [[Anonymize image files]] ===
Since images contain raw memory dumps people may refuse to send us images for debugging. Need to anonymize them, i.e. -- remove this sensitive information.
