                 impossible WHERE/HAVING clause
                 (subselect_single_select_engine::exec).

Allocation and initialization of joined table list t1, t2... of
subqueries like:

    NOT IN (SELECT ... FROM t1,t2,... WHERE 0)

is optimized out, however server tries to traverse this list.

Grouping or ordering of long values in not indexed BLOB/TEXT columns
with GBK or BIG5 charsets crashes the server.

MySQL server uses sorting (the filesort procedure) in the temporary
table to evaluate the GROUP BY clause in case of lack of suitable index.
That procedure takes into account only first @max_sort_length bytes
(system variable, usually 1024) of TEXT/BLOB sorting key string.
The my_strnxfrm_gbk and my_strnxfrm_big5 fill temporary keys
with data of whole blob length instead of @max_sort_length bytes
length. That buffer overrun has been fixed.

- Make convert_zerofill_number_to_string() take into account that the 
  constant it is converting may evaluate to NULL.

  1. Use 'dat' extension, because it is handled in Makefile.am;
  2. Fix typo: the bug id is 35469, not 35649.

- Backported the 5.1 DBUG to 5.0.
- Avoid memory cleanup race on Windows client for CTRL-C

The problem was that LOAD DATA code (sql_load.cc) didn't take into
account that there may be items, representing references to other
columns. This is a usual case in views. The crash happened because
Item_direct_view_ref was casted to Item_user_var_as_out_param,
which is not a base class.

The fix is to
  1) Handle references properly;
  2) Ensure that an item is treated as a user variable only when
     it is a user variable indeed;
  3) Report an error if LOAD DATA is used to load data into
     non-updatable column.

Mixing aggregate functions and non-grouping columns is not allowed in the
ONLY_FULL_GROUP_BY mode. However in some cases the error wasn't thrown because
of insufficient check.

In order to check more thoroughly the new algorithm employs a list of outer
fields used in a sum function and a SELECT_LEX::full_group_by_flag.
Each non-outer field checked to find out whether it's aggregated or not and
the current select is marked accordingly.
All outer fields that are used under an aggregate function are added to the
Item_sum::outer_fields list and later checked by the Item_sum::check_sum_func
function.

Fixed interference between tests: Users were added but not properly removed.
This caused later tests to fail.

Bug#21413
"Engine table handler used by multiple threads in REPLACE DELAYED"
When executing a REPLACE DELAYED statement, the storage engine
::extra() method was invoked by a different thread than the thread
which has acquired the handler instance.

This did not cause problems within the current server and with
the current storage engines.
But it has the potential to confuse future storage engines.

Added code to avoid surplus calls to extra() method in case of DELAYED
which avoids calling storage engine from a different thread than
expected.

No test case.
This change does not change behavior in conjunction with current
storage engines. So it cannot be tested by the regression test suite.

View definition as SELECT ... FROM DUAL WHERE ... has
valid syntax, but use of such view in SELECT or
SHOW CREATE VIEW syntax causes unexpected syntax error.

Server omits FROM DUAL clause when storing view body
string in a .frm file for further evaluation.
However, syntax of SELECT-witout-FROM query is more
restrictive than SELECT FROM DUAL syntax, and doesn't
allow the WHERE clause.

NOTE: this syntax difference is not documented.


View registration procedure has been modified to
preserve original structure of view's body.
