solver, db: repository pinning improvements 

* solver internally calculates now using tags; not repository masks
* installeddb now contains the tag name where the package came from
  -> we can now handle upgrades properly
* the pinning is still a preference, and not strictly enforced;
  versioned dependencies may overrule preference
