Common symbols with and without initialization

The crash happens because second filling of the same I_S table happens in
case of subselect with order by. table->sort.io_cache previously allocated
in create_sort_index() is deleted during second filling
(function get_schema_tables_result). There are two places where
I_S table can be filled: JOIN::exec and create_sort_index().
To fix the bug we should check if the table was already filled
in one of these places and skip processing of the table in second.

A view created with CREATE VIEW ... ORDER BY ... cannot be resolved with
the MERGE algorithm, even when no other part of the CREATE VIEW statement
would require the view to be resolved using the TEMPTABLE algorithm.

The check for presence of the ORDER BY clause in the underlying select is 
removed from the st_lex::can_be_merged() function.
The ORDER BY list of the underlying select is appended to the ORDER BY list

Objects of the class Item_equal contain an auxiliary member
eval_item of the type cmp_item that is used only for direct 
evaluation of multiple equalities. Currently a multiple equality
is evaluated directly only in the cases when the equality holds
at most for one row in the result set.
The compare collation of eval_item was determined incorectly.
It could lead to returning incorrect results for some queries.

The select_insert::send_eof() function now resets LAST_INSERT_ID variable if
no rows were inserted.

View check option clauses were ignored for updates of multi-table
views when the updates could not be performed on fly and the rows
to update had to be put into temporary tables first.

bug#25821  Excessive partition pruning for multi-range index scan in NDB API: post-review fix, added default value

with a column of the DATETIME type could return a wrong 
result set if the WHERE clause included a BETWEEN condition
on the column.
Fixed the method Item_func_between::fix_length_and_dec
where the aggregation type for BETWEEN predicates calculated
incorrectly if the first argument was a view column of the
DATETIME type.

Fix for bug#25821  Excessive partition pruning for multi-range index scan in NDB API: don't set distribution key if multi_range

INSERT ... ON DUPLICATE KEY UPDATE reports that a record was updated when
the duplicate key occurs even if the record wasn't actually changed
because the update values are the same as those in the record.

Now the compare_record() function is used to check whether the record was
changed and the update of a record reported only if the record differs
from the original one.

 Ignoring error codes from type conversion allows default (wrong) values to
 go unnoticed in the formation of index search conditions.
 Fixed by correctly checking for conversion errors.

This performance degradation for UPDATEs could be observed in the update
statements for which the search key cannot be converted to any valid
value of the type of the search column, like for a  the condition
int_fld=99999999999999999999999999, though it can be guaranteed here
that there is no row with such a key value.
