(BUG#40981 Maria: deadlock between checkpoint and maria_close() when freeing state info) storage/maria/ma_checkpoint.c: The argument added to the function to use it in maria_close(). storage/maria/ma_close.c: Locking/unlocking MARIA_SHARE::intern_lock added to use correct order of the mutexes taking. storage/maria/ma_state.c: Removed assert becase now we have externally locked mutex in maria_close(). The argument added to the _ma_remove_not_visible_states_with_lock() to use it in maria_close(). _ma_remove_not_visible_states_with_lock() fixed tio be usable from maria_chk where transaction manager is not initialized. storage/maria/ma_state.h: The argument added to the function to use it in maria_close(). storage/maria/maria_def.h: Fixed comment to the variable. storage/maria/trnman.c: The debugging assert added. New function to detect transaction manager initialization added (maria_chk do not initialize it). storage/maria/trnman_public.h: New function to detect transaction manager initialization added (maria_chk do not initialize it).
