Fix: "mysql --xml" now print NULL values the same way that "mysqldump --xml" does:
  
    <field name="name" xsi:nil="true" />
  
  to distinguish from empty strings:
  
    <field name="name"></field>
  
  and from string "NULL":
  
    <field name="name">NULL</field>

  Problem: for character sets having mbmaxlen==2,
  any ALTER TABLE changed TEXT column type to MEDIUMTEXT,
  due to wrong "internal length to create length" formula.
  Fix: removing rounding code introduced in early 4.1 time,
  which is not correct anymore.

  Adding a multibyte-aware VARCHAR copying function, to put correct column prefix,
  taking in account number of characters (instead just limiting on number of bytes).
  For example, for a KEY(col(3)) on a UTF8 column when copying the string 'foo bar foo',
  we should put only 3 leftmost characters: 'foo'.
  9 characters were incorrectly put before this fix.

containing a select statement that uses an aggregating IN subquery.
Added a parameter to the function fix_prepare_information 
to restore correctly the having clause for the second execution.
Saved andor structure of the having conditions at the proper moment
before any calls of split_sum_func2 that could modify the having structure
adding new Item_ref objects. (These additions, are produced not with 
the statement mem_root, but rather with the execution mem_root.)
