Fixed MDEV-3815: Aria engine return "The table is full" (ERROR 1114) inserting record, while MyISAM and InnoDB doesn't 

Increase default pointer length for Aria tables to be able to handle big files without having to specify MAX_ROWS


mysql-test/suite/maria/icp.result:
  Updated result
mysql-test/suite/maria/maria-preload.result:
  More pages are needed with longer pointer length
mysql-test/suite/maria/maria.result:
  Added more tests
mysql-test/suite/maria/maria.test:
  Added more tests
storage/maria/ma_create.c:
  Increase default pointer length for Aria tables to be able to handle big files without having to specify MAX_ROWS
storage/maria/ma_range.c:
  Optimize records_in_range() to be more exact
storage/maria/ma_static.c:
  Increase default pointer size
storage/maria/ma_test2.c:
  Allow a bit larger errors in records_in_range
