notifiers: Create and destroy nln_notifiers.

This patch changes the interface of netlink-notifier and
rtnetlink-link.  Now nln_notifiers are allocated and destroyed by
the module instead of passed in by callers.  This allows the
definition of nln_notifier to be hidden, and generally cleans up
the code.
