 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.

- 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)

  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).

If a set function with a outer reference s(outer_ref) cannot be aggregated 
the outer query against which the reference has been resolved then MySQL
interpretes s(outer_ref) in the same way as it would interpret s(const).
Hovever the standard requires throwing an error in this situation.
Added some code to support this requirement in ansi mode.
Corrected another minor bug in Item_sum::check_sum_func.

 to 0 causes wrong (large) length to be read
 from the row in _mi_calc_blob_length() when 
 storing NULL values in (e.g) POINT columns.
 This large length is then used to allocate
 a block of memory that (on some OSes) causes
 trouble.
 Fixed by calling the base class's 
 Field_blob::reset() from Field_geom::reset()
 that is called when storing a NULL value into
 the column.

from func_group.test after the patch for bug #27229 had been applied.
The memory corruption happened because in some rare cases the function
count_field_types underestimated the number of elements in
in the array param->items_to_copy.

context was used as an argument of GROUP_CONCAT.
Ensured correct setting of the depended_from field in references
generated for set functions aggregated in outer selects.
A wrong value of this field resulted in wrong maps returned by 
used_tables() for these references.
Made sure that a temporary table field is added for any set function
aggregated in outer context when creation of a temporary table is 
needed to execute the inner subquery.

When the DEFINER clause isn't specified in the ALTER statement then it's loaded
from the view definition. If the definer differs from the current user then
the error is thrown because only a super-user can set other users as a definers.

Now if the DEFINER clause is omitted in the ALTER VIEW statement then the
definer from the original view is used without check.

 in index search MySQL was not explicitly
 suppressing warnings. And if the context 
 happens to enable warnings (e.g. INSERT ..
 SELECT) the warnings resulting from converting 
 the data the key is compared to are 
 reported to the client.
 Fixed by suppressing warnings when converting
 the data to the same type as the key parts.

Patch appled after doing a pull from the team tree. Additional tests had to be
