Monty 1f18bd630a MDEV-8200 aria bug with insert select and lock tables
This bug happens when locking the same Aria "transactional" table
(page format) more then once with LOCK TABLES and inserting into one
of them with INSERT ... SELECT when the table is empty.

Fixed by ensuring we don't use fast bulk insert if table is opened
twice with LOCK TABLES (as this changes table->s->state)

Code changes:
- Added use_count to MARIA_USED_TABLES to be able to check if
  table is opened twice for a statement/lock table
- Don't clear history or reset info->start_state if we
  don't have versioning. One reason for the bug was
  was that info->start_state was set to point to different
  states for the two tables.  If there is no versioning
  info->start_state should always point to info->s->state.common.

Other things:
- Fixed also some typos that was noticed while scanning the code
- More DBUG_PRINT
