In order to make multi-delete SP friendly we need to have all table 
locks for the elements of main statement table list properly set 
at the end of parsing.

Also performed small cleanup: We don't need relink_tables_for_multidelete()
any longer since the only case now when TABLE_LIST::correspondent_table
is non-zero are tables in auxilary table list of multi-delete and these
tables are handled specially in mysql_multi_delete_prepare().

(Bug which caused its failure before was fixed in the beginning of March
 by the ChangeSet that introduced improved SP-locking).

We should not allow explicit or implicit transaction commits inside
of stored functions or triggers (so in autocommit mode we should not
do commits after execution of sub-statement).
Also since we don't support nested statement transactions in 5.0,
we shouldn't commit or rollback stmt transactions while we are inside
stored functions or triggers. This should be fixed in later (>=5.1)
releases.

The patch adds grammar support for LIMIT ?, ? and changes the
type of ST_SELECT_LEX::select_limit,offset_limit from ha_rows to Item*,
so that it can point to Item_param.

  Fixed bug #11088: a crash for queries with GROUP BY a BLOB column
  + COUNT(DISTINCT...) due to an attempt to allocate a too large
  buffer for the BLOB field.
  Now the size of the buffer is limited by max_sort_length.
group_by.test, group_by.result:
  Added a test case for bug #11088.
