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().


mysql-test/r/sp-threads.result:
  Added test case for bug #11158 "Can't perform multi-delete in stored
  procedure".
mysql-test/t/sp-threads.test:
  Added test case for bug #11158 "Can't perform multi-delete in stored
  procedure".
sql/mysql_priv.h:
  - Removed third argument from the declaration of multi_delete_precheck()
    as nowdays we calculate number of tables in multi-delete from which
    we are going to delete rows right at the end of statement parsing.
  - Introduced definition of multi_delete_set_locks_and_link_aux_tables()
    which is responsible for propagation of proper table locks from
    multi-delete's auxilary table list to the main list and binding
    corresponding tables in these two lists.
sql/sql_base.cc:
  Removed relink_tables_for_multidelete() routine and its invocations.
  We don't need them in 5.0 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().
sql/sql_lex.h:
  LEX::table_count
    Added description of new role of this LEX member for multi-delete. 
    Now for this statement we store number of tables from which we should
    delete records there.
sql/sql_parse.cc:
  multi_delete_precheck():
    Moved code which is responsible for iterating through auxilary table
    list and binding its elements with corresponding elements of main
    table list, and properly updating locks in it to separate function -
    multi_delete_set_locks_and_link_aux_tables(). This is because in order
    to make multi-delete SP friendly we need to have all locks set properly
    at the end of statement parsing. So we are introducing new function
    which will be called from parser.
    We also calculate number of tables from which we are going to perform
    deletions there and store this number for later usage in
    LEX::table_count.
    Also removed some no longer needed code.
sql/sql_prepare.cc:
  mysql_test_multidelete():
    Now multi_delete_precheck() takes only two arguments, so we don't
    need to pass fake third parameter.
sql/sql_yacc.yy:
  delete:
    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.

(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.


mysql-test/r/sp_trans.result:
  Added test for bug #10015 "Crash in InnoDB if stored routines are used"
  and for general transaction handling inside of functions.
mysql-test/t/sp_trans.test:
  Added test for bug #10015 "Crash in InnoDB if stored routines are used"
  and for general transaction handling inside of functions.
sql/handler.cc:
  ha_trans_commit()/ha_trans_rollback():
    Since we don't support nested statement transactions in 5.0,
    we can't commit or rollback stmt transactions while we are inside
    stored functions or triggers. So we simply do nothing now.
    This should be fixed in later ( >= 5.1) releases.
sql/item_func.cc:
  Item_func_sp::execute():
    Set THD::transaction.in_sub_stmt flag to TRUE during stored function
    execution to prevent commits and rollbacks for statement level
    transactions, since doing them will ruin such transaction for
    stateemtn which calls this function.
sql/share/errmsg.txt:
  Added error message which says that statements doing explicit or implicit
  commits are disallowed in triggers and stored functions.
sql/sql_base.cc:
  close_thread_tables():
    Clarified comment about committing of statement transactions in
    prelocked mode.
sql/sql_class.h:
  THD::transaction:
    Added in_sub_stmt method which indicates that we are executing
    statements from trigger or stored function now, and thus
    statement transaction belongs to statement which invoked this
    routine and we should not commit or rollback it while executing
    these sub-statements.
sql/sql_parse.cc:
  end_active_trans()/begin_trans()/end_trans():
    We should not commit or rollback global (non-stmt) transaction
    if we are executing stored function or trigger. These checks will
    catch situation when we are trying to do commit or rollback in stored
    procedure which is called from function or trigger.
sql/sql_trigger.h:
  Table_triggers_list::process_triggers():
    Set THD::transaction.in_sub_stmt flag to TRUE during trigger
    execution to prevent commits and rollbacks for statement level
    transactions, since doing them will ruin such transaction for
    stateemtn which invokes this trigger.
sql/sql_yacc.yy:
  Prohibited usage of statements which do explicit or implicit commit or
  rollback inside of stored functions and triggers.

 error for LIMIT placeholder".
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.


mysql-test/include/ps_modify.inc:
  Fix existing tests: now LIMIT can contain placeholders.
mysql-test/include/ps_query.inc:
  Fix existing tests: now LIMIT can contain placeholders.
mysql-test/r/ps.result:

  Fix test results: now LIMIT can contain placeholders.
mysql-test/r/ps_3innodb.result:

mysql-test/r/ps_7ndb.result:
  Fix test results: now LIMIT can contain placeholders.
mysql-test/t/ps.test:
  Add basic test coverage for LIMIT ?, ?.
sql/item.h:
  Add a short-cut for (ulonglong) val_int() to Item.
  Add a constructor to Item_int() that accepts ulonglong.
  Simplify Item_uint constructor by using the c-tor above.
sql/item_subselect.cc:
  Now select_limit has type Item *.
  We can safely create an Item in Item_exists_subselect::fix_length_and_dec():
  it will be allocated in runtime memory root and freed in the end of
  execution.
sql/sp_head.cc:
  Add a special initalization state for stored procedures to 
  be able to easily distinguish the first execution of a stored procedure
  from prepared statement prepare.
sql/sql_class.h:
  Introduce new state 'INITIALIZED_FOR_SP' to be able to easily distinguish
  the first execution of a stored procedure from prepared statement prepare.
sql/sql_derived.cc:
  - use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt
    evreryplace. Add a warning about use of set_limit in 
  mysql_derived_filling.
sql/sql_error.cc:
  - use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt
    evreryplace.
  - this change is also aware of bug#11095 "show warnings limit 0 returns 
  all rows instead of zero rows", so the one who merges the bugfix from
  4.1 can use local version of sql_error.cc.
sql/sql_handler.cc:
  - use unit->set_limit() to initalize 
  unit->select_limit_cnt,offset_limit_cnt everyplace.
sql/sql_lex.cc:
  Now ST_SELECT_LEX::select_limit, offset_limit have type Item *
sql/sql_lex.h:
  Now ST_SELECT_LEX::select_limit, offset_limit have type Item *
sql/sql_parse.cc:
  - use unit->set_limit() to initalize 
  unit->select_limit_cnt,offset_limit_cnt everyplace. 
  - we can create an Item_int to set global limit of a statement:
  it will be created in the runtime mem root and freed in the end of
  execution.
sql/sql_repl.cc:
  Use unit->set_limit to initialize limits.
sql/sql_select.cc:
  - select_limit is now Item* so the proper way to check for default value
  is to compare it with NULL.
sql/sql_union.cc:
  Evaluate offset_limit_cnt using the new type of ST_SELECT_LEX::offset_limit
sql/sql_view.cc:
  Now ST_SELECT_LEX::select_limit, offset_limit have type Item *
sql/sql_yacc.yy:
  Add grammar support for LIMIT ?, ? clause.
