Insert log entries in batches

Store log lines in memory until threshold is reach or idle occurs, then
insert all the lines in a single transaction. Save points handle the
case of insertion errors. On success the queue is cleared.
Parked lines also saved in bulk, only necessary if queued lines could
not be inserted on shutdown, else the queue simply grows until ability
to insert is restored. Importing parked lines just adds them to the
queue and the normal process then follows.
