Olivier Bertrand 1904284361 This commit brings many changes, in particular two important ones:
1) Support of partitioning by connect. A table can be partitioned
   by files, this is an enhanced MULTIPLE table. It can be also
   partitioned by sub-tables like TBL and this enables table sharding.
2) Handling a CONNECT bug that causes in some cases extraneous rows
   to remain in the table after an UPDATE or DELETE when the command
   uses indexing (for not fixed file tables). Until a real fix is
   done, CONNECT tries to ignore indexing and if it cannot do it
   abort the command with an error message.

- Add tests on partitioning
added:
  storage/connect/mysql-test/connect/r/part_file.result
  storage/connect/mysql-test/connect/r/part_table.result
  storage/connect/mysql-test/connect/t/part_file.test
  storage/connect/mysql-test/connect/t/part_table.test

- Temporary fix
modified:
  sql/sql_partition.cc

- Add functions ha_connect::IsUnique and ha_connect::CheckColumnList
modified:

- Prevent updating a partition table column that is part of
  the partition function (outward tables only)
modified:
  storage/connect/ha_connect.cc

- Support INSERT/UPDATE/DELETE for PROXY tables
modified:
  storage/connect/tabutil.cpp

- Handle the bug on updating rows via indexing. Waiting for a real fix,
  Don't use indexing when possible else raise an error and abort.
