Problem: setting/displaying @@LC_TIME_NAMES didn't distinguish between
GLOBAL and SESSION variable types - always SESSION variable
was set/shonw.
Fix: set either global or session value.
Also, "mysqld --lc-time-names" was added to set "global default" value.

Pushbuild fixes: 
 - Make MAX_SEL_ARGS smaller (even 16K records_in_range() calls is 
   more than it makes sense to do in typical cases)
 - Don't call sel_arg->test_use_count() if we've already allocated 
   more than MAX_SEL_ARGs elements. The test will succeed but will take
   too much time for the test suite (and not provide much value).

NO_AUTO_VALUE_ON_ZERO mode.

In the NO_AUTO_VALUE_ON_ZERO mode the table->auto_increment_field_not_null
variable is used to indicate that a non-NULL value was specified by the user
for an auto_increment column. When an INSERT .. ON DUPLICATE updates the
auto_increment field this variable is set to true and stays unchanged for the
next insert operation. This makes the next inserted row sometimes wrongly have
0 as the value of the auto_increment field.

Now the fill_record() function resets the table->auto_increment_field_not_null
variable before filling the record.
The table->auto_increment_field_not_null variable is also reset by the
open_table() function for a case if we missed some auto_increment_field_not_null
handling bug.
Now the table->auto_increment_field_not_null is reset at the end of the
mysql_load() function.

Reset the table->auto_increment_field_not_null variable after each
write_row() call in the copy_data_between_tables() function.

 When creating a temporary table the concise column type
 of a string expression is decided based on its length:
 - if its length is under 512 it is stored as either 
   varchar or char.
 - otherwise it is stored as a BLOB.
 
 There is a flag (convert_blob_length) to create_tmp_field 
 that, when >0 allows to force creation of a varchar if the
 max blob length is under convert_blob_length.
 However it must be verified that convert_blob_length 
 (settable through a SQL option in some cases) is 
 under the maximum that can be stored in a varchar column.
 While performing that check for expressions in 
 create_tmp_field_from_item the max length of the blob was
 used instead. This causes blob columns to be created in the
 heap temp table used by GROUP_CONCAT (where blobs must not
 be created in the temp table because of the constant 
 convert_blob_length that is passed to create_tmp_field() ).
 And since these blob columns are not expected in that place
 we get wrong results.
 Fixed by checking that the value of the flag variable is 
 in the limits that fit into VARCHAR instead of the max length
 of the blob column.

- Added PARAM::alloced_sel_args where we count the # of SEL_ARGs
  created by SEL_ARG tree cloning operations.
- Made the range analyzer to shortcut and not do any more cloning 
  if we've already created MAX_SEL_ARGS SEL_ARG objects in cloning.
- Added comments about space complexity of SEL_ARG-graph 
  representation.

When OPTIMIZE TABLE is completed it attempts to rename temporary
file to original name. This step may fail on windows when a file
is opened. As a result data file might be deleted and optimized
copy of file (table_name.MYD) remains.

This situation is handled properly by my_delete_allow_opened, so
use it instead of my_delete when attempting to rename a file on
windows.

No suitable test case for this bug.

- Define Sql_alloc::operator new() as thow() so that C++ compiler
  handles NULL return values
(there is no testcase as there is no portable way to set limit on the 
amount of memory that a process can allocate)

Problem: SOUNDEX returned an invalid string for international
characters in multi-byte character sets.
For example: for a Chinese/Japanese 3-byte long character
_utf8 0xE99885 it took only the very first byte 0xE9,
put it into the outout string and then appended with three 
DIGIT ZERO characters, so the result was 0xE9303030 - which
is an invalide utf8 string.
Fix: make SOUNDEX() multi-byte aware and - put only complete
characters into result, thus return only valid strings.
This patch also makes SOUNDEX() compatible with UCS2.

  Geometry fields have a result type string and a 
  special subclass to cater for the differences
  between them and the base class (just like 
  DATE/TIME).
  When creating temporary tables for results of 
  functions that return results of type GEOMETRY
  we must construct fields of the derived class 
  instead of the base class.
  Fixed by creating a GEOMETRY field (Field_geom) 
  instead of a generic BLOB (Field_blob) in temp 
  tables for the results of GIS functions that 
  have GEOMETRY return type (Item_geometry_func).
