Open all active LWG deferred items at priority 4, clearing priorty 5
to be used to signal extension requests.  We will use priority 5 to
indicate when LEWG throw an issue back to LWG to wordsmith and adopt,
when the issues lists handling seems appropriate for dealing with
tiny requests.

Also applied NAD status for any Tentatively or Pending NAD issues.
Have not checked the draft for Editorial issues, so left those in
Pending/Tentative status.
