fix(ddl): MCOL-5974 TIMESTAMP columns are not IS NOT NULL by default in MCS ( #3670 )
...
The old behavior was to assign TIMESTAMP columns an IS NOT NULL
constraint if list of constraints was empty. Apparently, this particular
invariant was changed in 11.4 and bugfixes' mcol-5480.test started to
fail.
This patch fixes behavioral difference and reenables mcol-5480 test in
11.4.

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
