MEDIUM: dumpstats/pattern: display and use each pointer of each pattern dumped

Browse Source 
Each pattern displayed is associated to the value of his pattern
reference. This value can be used for deleting the entry. It is useful
with complex regex: the users are not forced to write the regex with all
the amiguous chars and escaped chars on the CLI.
