Compaction, retain and recovery

Browse source 
Change the penciller check so that it returns current/replaced/missing not just true/false.

Reduce unnecessary penciller checks for non-standard keys that will always be retained - and remove redunandt code.

Expand tests of retain and recover to make sure that compaction on delete is well covered.

Also move the SQN number laong during initial loads - to stop aggressive loop to find starting SQN every file.
