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.

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

fix: MCOL-5755: incorrect handling of BLOB (and TEXT) in GROUP BY
...
BLOB fields did not work as grouping keys at all, they were assigned
value NULL for any value, be it NULL or not. The fix is in the
rowaggregation.cpp in the initMapping(), a switch/case branch was added
to handle BLOB field copying there.
Also, TEXT columns did not distinguish between NULL and empty string in
the grouping algorithm, now they do. The fix is in the equals()
function, now we specifically check for isNull() equality between
values.

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.

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.
