Error was emitted when one tried to select information from view which used
merge algorithm and which also had CONVERT_TZ() function in its select list.

This bug was caused by wrong assumption that global table list for view
which is handled using merge algorithm begins from tables belonging to
the main select of this view. Nowadays the above assumption is not true only
when one uses convert_tz() function in view's select list, but in future
other cases may be added (for example we may support merging of views
with subqueries in select list one day). Relying on this false assumption
led to the usage of wrong table list for field lookups and therefor errors. 

With this fix we explicitly use pointer to the beginning of main select's
table list.


mysql-test/r/timezone_grant.result:
  Added additional test case for bug#15153 "CONVERT_TZ() is not allowed in
  all places in VIEWs" that checks that usage of CONVERT_TZ() function in view
  does not require additional privileges.

The bug caused wrong result sets for union constructs of the form
(SELECT ... ORDER BY order_list1 [LIMIT n]) ORDER BY order_list2.
For such queries order lists were concatenated and limit clause was
completely neglected. 


mysql-test/r/order_by.result:
  Added a test case for bug #18767.

  Changed the condition on which a SELECT is treated as part of a UNION.

  now is handled in the same way as the first SELECT in a UNION
  sequence.
sql/sql_union.cc:

sql/sql_yacc.yy:
  Fixed bug #18767.
  Changed the condition at which a SELECT is treated as part of a UNION.
  The SELECT in 
  (SELECT ... ORDER BY order_list1 [LIMIT n]) ORDER BY order_list2 
  now is handled in the same way as the first SELECT in a UNION
  sequence. In the same way is handled the SELECT in
  (SELECT ... LIMIT n) ORDER BY order list.
  Yet if there is neither ORDER BY nor LIMIT in the single-select
  union construct
  (SELECT ...) ORDER BY order_list
  then it is still handled as simple select with an order clause.

The SQL standard doesn't allow to use in HAVING clause fields that are not 
present in GROUP BY clause and not under any aggregate function in the HAVING
clause. However, mysql allows using such fields. This extension assume that 
the non-grouping fields will have the same group-wise values. Otherwise, the 
result will be unpredictable. This extension allowed in strict 
MODE_ONLY_FULL_GROUP_BY sql mode results in misunderstanding of HAVING 
capabilities.

The new error message ER_NON_GROUPING_FIELD_USED message is added. It says
"non-grouping field '%-.64s' is used in %-.64s clause". This message is
supposed to be used for reporting errors when some field is not found in the
GROUP BY clause but have to be present there. Use cases for this message are 
this bug and when a field is present in a SELECT item list not under any 
aggregate function and there is GROUP BY clause present which doesn't mention 
that field. It renders the ER_WRONG_FIELD_WITH_GROUP error message obsolete as
being more descriptive.
The resolve_ref_in_select_and_group() function now reports the 
ER_NON_GROUPING_FIELD_FOUND error if the strict mode is set and the field for 
HAVING clause is found in the SELECT item list only.



sql/share/errmsg.txt:
  Added the new ER_NON_GROUPING_FIELD_USED error message for the bug#14169.
mysql-test/t/having.test:
  Added test case for the bug#18739:  non-standard HAVING extension was allowed in strict ANSI sql mode.
mysql-test/r/having.result:

sql/sql_select.cc:
  Added TODO comment to change the ER_WRONG_FIELD_WITH_GROUP to more detailed ER_NON_GROUPING_FIELD_USED message.
sql/item.cc:
  Fixed bug#18739: non-standard HAVING extension was allowed in strict ANSI sql mode.
  The resolve_ref_in_select_and_group() function now reports the
  ER_NON_GROUPING_FIELD_FOUND error if the strict MODE_ONLY_FULL_GROUP_BY mode
  is set and the field for HAVING clause is found in the SELECT item list only.
