Now that scanning is supported and PANs properly registered, give
certain rights to the user, such as listing asynchronously the listed
PANs as well as flushing the list.

The maximum number of PANs to list and their delay before expiration can
be configured. By default there is no limit. When these parameters are
set, PANs are automatically dropped from the list.

These two helpers were defined within the experimental section. I will
move them out of this section now that they have other users than
experimental code.
