conditions.
When allocating memory for KEY_FIELD/SARGABLE_PARAM structures the
function update_ref_and_keys did not take into account the fact that
a single row equality could be replaced by several simple equalities.
Fixed by adjusting the counter cond_count accordingly for each subquery
when performing substitution of a row equality for simple equalities.

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.
