The problem was in an incorrect debug assertion. The expression 
used in the failing assertion states that when finding 
references matching ORDER BY expressions, there can be only one 
reference to a single table. But that does not make any sense, 
all test cases for this bug are valid examples with multiple 
identical WHERE expressions referencing the same table which
are also present in the ORDER BY list. 
 
Fixed by removing the failing assertion. We also have to take 
care of the 'found' counter so that we count multiple 
references only once. We rely on this fact later in 
eq_ref_table().

Two result files in the sys_vars suite wasn't 
properly updated after the change in
deprecation text

"TYPE=storage_engine" is deprecated, and will be removed
in the Celosia release of MySQL.  Since the option is
present in the Betony release and the version number of
Celosia is still not decided, we need to bump the
deprecation version number back up to "6.0".

MySQL with gcc 4.3.2
      
This is the final patch in the context of this bug. 

When EXPLAIN EXTENDED tries to print column names, it checks whether the
referenced table is CONST (in which case, the column's value rather than
its name will be printed). If no proper table is reference (i.e. because
a derived table was used that has since gone out of scope), this will fail
spectacularly.

This ports an equivalent of the fix for Bug 43354.

CHECK_FIELD_IGNORE was treated as CHECK_FIELD_ERROR_FOR_NULL;
UPDATE...SET...NULL on NOT NULL fields behaved differently after
a trigger.

Now distinguishes between IGNORE and ERROR_FOR_NULL and save/restores
check-field options.

Fixed the test to behave correctly with ps-protocol
and binlog format row.

Added --max-connections= argument to mysqltest and mtr
Small fix to first patch: forgot to check before free'ing connections array

Table corruption happens during table reading in ha_tina::find_current_row() func.
Field::store() method returns error(true) if stored value is 0.
The fix:
added special case for enum type which correctly processes 0 value.
Additional fix:
INSERT...(default) and INSERT...() have the same behaviour now for enum type.

Some logic would group by suite always
Disable this if using --noreorder
Also fix getting array from collect_one_suite() in this case
Amended according to previous comment

A "%define" is no shell command, so it must not be the
only line in the "then" or "else" branch of an "if".

Add a ':' line to make the branch non-empty.

due to ifdef of include file

The problem is that during temporary table creation uneven bits
are not taken into account for hidden fields. It leads to incorrect
calculation&allocation of null bytes size for table record. And
if grouped value is null we set wrong bit for this value(see end_update()).
Fixed by adding separate calculation of uneven bit for hidden fields.

Fixed a compilation warning.

This bug is just one facet of stored routines not being able to
detect changes in meta-data (WL#4179). This particular problem
can be triggered within a single session due to the improper
management of the pre-locking list if the view is expanded after
the pre-locking list is calculated.

Since the overall solution for the meta-data detection issue is
planned for a later release, for now a workaround is used to
fix this particular aspect that only involves a single session.
The workaround is to flush the thread-local stored routine cache
every time a view is created or modified, causing locally cached
routines to be re-evaluated upon invocation.

Fixed several (obvious) places that don't work with vpath
build.
