init: add --skip-artnum parameter

For archivists with only newer mail archives, this option allows
reserving reserve NNTP article numbers for yet-to-be-archived
old messages.  Indexers will need to be updated to support this
feature in future commits.

-V1 inboxes will now be initialized with SQLite and Xapian
support if this option is used, or if --indexlevel= is
specified.
