counter".

When TRUNCATE TABLE was called within an stored procedure the
auto_increment counter was not reset to 0 even if straight
TRUNCATE for this table did this.

This fix makes TRUNCATE in stored procedures to be handled exactly
in the same way as straight TRUNCATE. We achieve this by rolling
back the fix for bug 8850, which is no longer needed since stored
procedures don't require prelocked mode anymore (and TRUNCATE is
not allowed in stored functions or triggers).

  Backporting a 5.0 change:
  MAX_BUF was too small for Index.xml
  Changeing MAX_BUF and adding assert to easier
  catch the same problem in the future.

  Regenerating ctype-extra.c with the fixed conf_to_src.

  Buffer was too small to load Index.xml.
  So some charsets were not gerenrated.
  Making the buffer bigger, and adding an DBUG_ASSERT,
  to easier catch the problem in the future.
ctype-extra.c:
  Additional charsets were generated.

Mutli-table uses temporary table to store new values for fields. With the
new values the rowid of the record to be updated is stored in a Field_string
field. Table to be updated is set as source table of the rowid field.
But when the temporary table creates the tmp field for the rowid field it
converts it to a varstring field because the table to be updated was created by
the v4.1. Due to this the stored rowids were broken and no records for 
update were found.

The flag can_alter_field_type is added to Field_string class. When it is set to
0 the field won't be converted to varstring. The Field_string::type() function 
now always returns MYSQL_TYPE_STRING if can_alter_field_type is set to 0.
The multi_update::initialize_tables() function now sets can_alter_field_type
flag to 0 for the rowid fields denying conversion of the field to a varstring
field.

The code in opt_sum_query that prevented the COUNT/MIN/MAX 
optimization from being applied to outer joins  was not adjusted 
after introducing nested joins. As a result if an outer join
contained a reference to a view as an inner table the code of
opt_sum_query missed the presence of an on expressions and
erroneously applied the mentioned optimization.
