* 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

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.
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.
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.
The fix is simple: enable subtotals in single-phase aggregation and
disable parallel processing when there are subtotals and aggregation is
single-phase.
* chore(build): refactor main CMakeLists.txt
* chore(build): fix boost version for packages, set clang-20 only for amd and arm
* chore(build): boost 4 sm
* chore(build): boost dep for rowgroup
* chore(build): toolset for boost
* chore(build): suppress clang warnings for boost
* chore(ci, build): use ASAN for unittest on ubuntu 24.04 only, added custom cmake flag option for bootstrap, custom params for new and existing pipelines
* chore(build): sort bootstrap flags
* chore(CI): remove publish pkg step, adding clickable link instead to publish steps, fix customenv
The purpose of this changeset is to obtain list of partitions from
SELECT_LEX structure and pass it down to joblist and then to
CrossEngineStep to pass to InnoDB.
* move GROUP_CONCAT/JSON_ARRAYAGG storage to the RowGroup from
the RowAggregation*
* internal data structures (de)serialization
* get rid of a specialized classes for processing JSON_ARRAYAGG
* move the memory accounting to disk-based aggregation classes
* allow aggregation generations to be used for queries with
GROUP_CONCAT/JSON_ARRAYAGG
* Remove the thread id from the error message as it interferes with the mtr
