Kentoku SHIBA e53ef202bd Adding direct update/delete to the server and to the partition engine. ...

Add support for direct update and direct delete requests for spider.
A direct update/delete request handles all qualified rows in a single
operation rather than one row at a time.

Contains Spiral patches:
006_mariadb-10.2.0.direct_update_rows.diff      MDEV-7704
008_mariadb-10.2.0.partition_direct_update.diff MDEV-7706
010_mariadb-10.2.0.direct_update_rows2.diff     MDEV-7708
011_mariadb-10.2.0.aggregate.diff               MDEV-7709
027_mariadb-10.2.0.force_bulk_update.diff       MDEV-7724
061_mariadb-10.2.0.mariadb-10.1.8.diff          MDEV-12870

- The differences compared to the original patches:
  - Most of the parameters of the new functions are unnecessary.  The
    unnecessary parameters have been removed.
  - Changed bit positions for new handler flags upon consideration of
    handler flags not needed by other Spiral patches and handler flags
    merged from MySQL.
  - Added info_push() (Was originally part of bulk access patch)
  - Didn't include code related to handler socket
  - Added HA_CAN_DIRECT_UPDATE_AND_DELETE
