  Post fix for bug#28494.
  The Item_func_set_user_var::check method now silently doesn't use result_field
  if it isn't defined.

This is an additional fix.
Item::val_xxx methods are supposed to use original data source and
Item::val_xxx_result methods to use the item's result field. But for the
Item_func_set_user_var class val_xxx_result methods were mapped to val_xxx
methods. This leads, in particular, to producing bad sort keys and thus
wrong order of the result set of queries with group by/order by clauses.

The set of val_xxx_result methods is added to the Item_func_set_user_var
class. It's the same as the val_xxx set of method but uses the result_field
to return a value.

To avoid unnecessary work the mysql_alter_table function takes the
list of table fields and applies all changes to it (drops/moves/renames/etc).
Then this function compares the new list and the old one. If the changes
require only .frm to be modified then the actual data isn't copied. To detect
changes all columns attributes but names are compared. When a column has been
moved and has replaced another column with the same attributes except name
the mysql_alter_table function wrongly decides that two fields has been just
renamed. As a result the data from the moved column and from all columns
after it is not copied.

Now the mysql_alter_table function forces table data copying by setting
the need_copy_table flag when it finds a moved column. The flag is set at
the stage when the modified fields are created.

  Additional patch for bug #28244 to workaround valgrind warnings.

into  moonbone.local:/mnt/gentoo64/work/28494-bug-5.0-opt-mysql

The end_update() function uses the Item::save_org_in_field() function to
save original values of items into the group buffer. But for the 
Item_func_set_user_var this method was mapped to the save_in_field method.
The latter function wrongly decides to use the result_field. This leads to
saving incorrect value in the grouping buffer and wrong result of the whole
query.

The can_use_result_field argument of the bool type is added to the
Item_func_set_user_var::save_in_field() function. If it is set to FALSE
then the item's result field won't be used. Otherwise it will be detected
whether the result field will be used (old behaviour).
Two wrapping functions for the function above are added to the 
Item_func_set_user_var class:
the save_in_field(Field *field, bool no_conversions) - it calls the above
function with the can_use_result_field set to TRUE.
the save_org_in_field(Field *field) - same, but the can_use_result_field
is set to FALSE.

ON conditions from JOIN expression were ignored at CHECK OPTION
check when updating a multi-table view with CHECK OPTION.

The st_table_list::prep_check_option function has been
modified to to take into account ON conditions at CHECK OPTION check
It was also changed to build the check option condition only once
for any update used in PS/SP.

When the same VIEW was created at the master side twice,
malformed (truncated after the word 'AS') query string 
was forwarded to client side, so error messages on the
master and client was different, and replication was
broken.

The mysql_register_view function call failed
too early: fields of `view' output argument of this 
function was not filled yet with correct data required
for query replication.
The mysql_register_view function also copied pointers to 
local buffers into a memory allocated by the caller.

problem #1: udf_example.so does not get built on AIX

solution#1: build it yourself using
cd sql; gcc  -g -I ../include/ -I /usr/include/ -lpthread  \
-shared -o udf_example.so udf_example.c; mv udf_example.so \
.libs/ 

problem#2 (the bug): udf_example fails because it does not
recognize the variable LD_LIBRARY_PATH when doing dl_open(),
it looks at LIBPATH

solution#2: add the library path to LIBPATH

problem#3: udf_example returns the wrong result length since 
it relies on strmov to return a pointer to the end of the 
string that it copies. On AIX builds, where m_string.h is not
included (m_string defines a macro expanding strmov to stpcpy),
there is a macro expanding strmov to strcpy, which returns a 
pointer to the first character.

solution#3: define strmov as stpcpy.

problem#4: #2 applies on hp-ux as well, but this platform
looks at SHLIB_PATH

solution#4: added the library path to SHLIB_PATH

mysqld crashed when a long-running explain query was killed from
another connection.

When the current thread caught a kill signal executing the function
best_extension_by_limited_search it just silently returned to  
the calling function greedy_search without initializing elements of
the join->best_positions array.
However, the greedy_search function ignored thd->killed status
after a calls to the best_extension_by_limited_search function, and
after several calls the greedy_search function used an uninitialized
data from the join->best_positions[idx] to search position in the
join->best_ref array. 
That search failed, and greedy_search tried to call swap_variables
function with NULL argument - that caused a crash.
