Contains Spiral patches:
- Spiral Patch 022: 022_mariadb-10.2.0.auto_increment.diff          MDEV-7720
- Spiral Patch 030: 030_mariadb-10.2.0.partition_auto_inc_init.diff MDEV-7726

These patches have the following differences compared to the original patches:
- Added the new #defines for the feature in ha_spider.h instead of in handler.h
  because these #defines are needed by Spider and are not needed by the server.
- Added a test case.
- Added test result changes resulting from a bug that was fixed by these
  patches.
