Fix introduces unique_ptr around DBRM instance in fill result functions.
Now all paths lead to DBRM instance freeing.

3a91cded27 chore(MCOL-6018) Fix incorrect Field_decimal cast
This is a fix of a problem found by UBSAN. MDB changed default type to
represent a decimal result, C-style cast did not do proper type checking
and this one-liner fixes that. Now we will have an assertion if type
changes again.

dc4ca8d588 MCOL-5943: MCOL-4740 update rows counter for multi-table update (#3555)
* fix(plugin): MCOL-4740: This fixes update rows counter for multi-table update
For UPDATEs involving a single table, the server call to handler::direct_update_rows() is used to correctly set the count for the number of updated rows in the UPDATE statement.
However, for UPDATEs involving multi-tables, the server does not call handler::direct_update_rows(). This patch adds support to correctly report the number of updated rows to the client by setting
multi_update::updated and multi_update::found in handler::rnd_end().

* fix(plugin): MCOL-4740: this is to addres the original patch QA found in the original patch

bfe49a8345 bug(priproc) make last_day type a bit more accurate
This fixes discrepance with the server, which assigns DATE type to
last_day()'s result.

Now we also assigns DATE result type and, also, use proper
dataconvert::Day data structure to return date.

Tests agree with InnoDB.

Also, this patch includes test for MCOL-5669, to show we fixed it.

ef451af860 feat(ddl): MCOL-5744: better handling of utf8 charset aliases (#3174)
Server expands ut8_XXX aliases to utf8mb3_XXX or utf8mb4_XXX depending
on the UTF8_IS_UTF8MB3 setting in the OLD_MODE environment variable.

Server already has the necessary code implemented in the get_utf8_flag()
method of class THD. There are several uses of this flag and all we have
to do to be in line with server is to use it.

This patch does that for DDL as work on MCOL-5705 uncovered some
problems in that area.

5f6080e09c fix(join): Fixes MCOL-5056, an error of joining TEXT column from InnoDB (#3160)
We incorrectly identified TEXT columns from external tables as BLOB.
Alexander Barkov suggested a way to discriminate them which I
implemented here.
