b5534eb847 MCOL-641 Refactored MultiplicationOverflowCheck but it still has flaws. 
Introduced fDecimalOverflowCheck to enable/disable overflow check.

Add support into a FunctionColumn.

Low level scanning crashes on medium sized data sets.

74b64eb4f1 MCOL-641 1. Add support for int128_t in ParsedColumnFilter. 
2. Set Decimal precision in SimpleColumn::evaluate().
3. Add support for int128_t in ConstantColumn.
4. Set IDB_Decimal::s128Value in buildDecimalColumn().
5. Use width 16 as first if predicate for branching based on decimal width.

0ff0472842 MCOL-641 sum() now works with DECIMAL(38) columns. 
TupleAggregateStep class method and buildAggregateColumn() now properly set result data type.

doSum() now handles DECIMAL(38) in approprate manner.

Low-level null related methods for new binary-based datatypes now handles magic values for
binary-based DT.

35c4b66a67 MCOL-4144 Enable lower_case_table_names 
Create tables and schemas with lower case name only if the flag is set.
During operations, convert to lowercase in plugin. Byt the time a query gets to ExeMgr, DDLProc etc., everything must be lower case if the flag is set, and undisturbed if not.

a117786027 MCOL-4282 Enable Select Handler for Prepared Statements 
This patch enables select handler for executing prepared
statements. Most importantly, we are now activating a
persistent arena which will allocate any new items in a
permanent MEMROOT for prepared statements and stored procedures.
Refer to JOIN::optimize_inner() for details.

In processWhere(), we now use SELECT_LEX::prep_where in case
we are executing a prepared statement, as this is where the saved
WHERE clause is stored for prepared statement processing.

In addition, we also disable derived handler for prepared
statements.

01ff2652a6 MCOL-4023 Pushdown WHERE conditions for UPDATE/DELETE. 
For certain queries, such as:
  update cs1 set i = 41 where i = 42 or (i is null and 42 is null);
the SELECT_LEX.where does not contain the required where conditions.
Server sends the where conditions in the call to cond_push(), so
we are storing them in a handler data member, condStack, and later
push them down to getSelectPlan() for UPDATES/DELETEs.

e7bc7e9313 MCOL-3924 Use the first parse error found 
Often, after an error is found, it cascades into a bunch of errors, and each overwrites the previous. This sometimes obfuscates the true problem.

ab2003baaa MCOL-3903 Enable Select Handler to run query part of INSERT..SELECT. 
Original SH implementation sends the result set back to the client
thus it can't be used in INSERT..SELECT, SELECT INTO OUTFILE,CREATE
TABLE AS SELECT etc.
CLX-77 feature has been backported into MDB to enable SH to run
query part of the mentioned queries.
