MySQL uses _beginthread()/_endthread() instead of 
_beginthreadex()/_endthreadex() to create/end its threads
on Windows.
According to MSDN  _endthread() does close the thread handle.
So there's no need the handle to be closed explicitly.
Besides : WaitForSingleObject(, INFINITE) != WAIT_OBJECT_0) is
true for all practical cases as the other two possible return 
codes (according to MSDN) cannot happen in that case the 
CloseHandle() was actually a dead code.
Fixed by removing the CloseHandle() call. No test case added
because it's not possible to test for absence of dead code. 


include/my_pthread.h:
  Bug #26564: Don't call CloseHandle since we use 
  beginthread/endthread instead of beginthreadex/endthreadex.

the loose scan optimization for grouping queries was applied returned 
a wrong result set when the query was used with the SQL_BIG_RESULT
option.

The SQL_BIG_RESULT option forces to use sorting algorithm for grouping
queries instead of employing a suitable index. The current loose scan
optimization is applied only for one table queries when the suitable
index is covering. It does not make sense to use sort algorithm in this
case. However the create_sort_index function does not take into account
the possible choice of the loose scan to implement the DISTINCT operator
which makes sorting unnecessary. Moreover the current implementation of
the loose scan for queries with distinct assumes that sorting will
never happen. Thus in this case create_sort_index should not call
the function filesort.

INSERT into table from SELECT from the same table
with ORDER BY and LIMIT was inserting other data
than sole SELECT ... ORDER BY ... LIMIT returns.

One part of the patch for bug #9676 improperly pushed
LIMIT to temporary table in the presence of the ORDER BY

That part has been removed.

The C optimizer may decide that data access operations
through pointer of different type are not related to 
the original data (strict aliasing).
This is what happens in fetch_long_with_conversion(),
when called as part of mysql_stmt_fetch() : it tries 
to check for truncation errors by first storing float
(and other types of data) into a char * buffer and then 
accesses them through a float pointer.
This is done to prevent the effects of excess precision
when using FPU registers.
However the doublestore() macro converts a double pointer
to an union pointer. This violates the strict aliasing rule.
Fixed by making the intermediary variables volatile (
to not re-introduce the excess precision bug) and using
the intermediary value instead of the char * buffer.
Note that there can be loss of precision for both signed
and unsigned 64 bit integers converted to double and back,
so the check must stay there (even for compatibility 
reasons).
Based on the excellent analysis in bug 28400.
