Changes needed for ColumnStore and insert cache

MCOL-3875 Columnstore write cache

The main change is to change thr_lock function get_status to
return a value that indicates we have to abort the lock.

Other thing:
- Made start_bulk_insert() and end_bulk_insert() protected so that the
  insert cache can use these
