 SELECT statement itself returns empty.

As a result of this bug 'SELECT AGGREGATE_FUNCTION(fld) ... GROUP BY'
can return one row instead of an empty result set.

When GROUP BY only has fields of constant tables
(with a single row), the optimizer deletes the group_list.
After that we lose the information about whether we had an
GROUP BY statement. Though it's important
as SELECT min(x) from empty_table; and
   SELECT min(x) from empty_table GROUP BY y; have to return
different results - the first query should return one row,
second - an empty result set.
So here we add the 'group_optimized_away' flag to remember this case
when GROUP BY exists in the query and is removed
by the optimizer, and check this flag in end_send_group()

Bug #27417 thd->no_trans_update.stmt lost value inside of SF-exec-stack
  
Once had been set the flag might later got reset inside of a stored routine 
execution stack.
The reason was in that there was no check if a new statement started at time 
of resetting.
The artifact affects most of binlogable DML queries. Notice, that multi-update 
is wrapped up within
  bug@27716 fix, multi-delete bug@29136.
  
Fixed with saving parent's statement flag of whether the statement modified 
non-transactional table, and unioning (merging) the value with that was gained 
in mysql_execute_command.
  
Resettling thd->no_trans_update members into thd->transaction.`member`;
Asserting code;
Effectively the following properties are held.
  
1. At the end of a substatement thd->transaction.stmt.modified_non_trans_table
   reflects the fact if such a table got modified by the substatement.
   That also respects THD::really_abort_on_warnin() requirements.
2. Eventually thd->transaction.stmt.modified_non_trans_table will be computed as
   the union of the values of all invoked sub-statements.
   That fixes this bug#27417;

Computing of thd->transaction.all.modified_non_trans_table is refined to base to 
the stmt's value for all the case including insert .. select statement which 
before the patch had an extra issue bug@28960.
Minor issues are covered with mysql_load, mysql_delete, and binloggin of insert in
to temp_table select. 
  
The supplied test verifies limitely, mostly asserts. The ultimate testing is defered
for bug@13270, bug@23333.

When innodb detects a deadlock it calls ha_rollback_trans() to rollback the 
main transaction. But such action isn't allowed from inside of triggers and
functions. When it happen the 'Explicit or implicit commit' error is thrown
even if there is no commit/rollback statements in the trigger/function. This
leads to the user confusion.

Now the convert_error_code_to_mysql() function doesn't call the 
ha_rollback_trans() function directly but rather calls the
mark_transaction_to_rollback function and returns an error.
The sp_rcontext::find_handler() now doesn't allow errors to be caught by the
trigger/function error handlers when the thd->is_fatal_sub_stmt_error flag
is set. Procedures are still allowed to catch such errors.
The sp_rcontext::find_handler function now accepts a THD handle as a parameter.
The transaction_rollback_request and the is_fatal_sub_stmt_error flags are 
added to the THD class. The are initialized by the THD class constructor.
Now the ha_autocommit_or_rollback function rolls back main transaction
when not in a sub statement and the thd->transaction_rollback_request
is set.
The THD::restore_sub_statement_state function now resets the 
thd->is_fatal_sub_stmt_error flag on exit from a sub-statement.

SP with local variables with non-ASCII names crashed the server.

The server replaces SP local variable names with NAME_CONST calls
when putting statements into the binary log. It used UTF8-encoded
item names as variable names for the replacement inside NAME_CONST
calls. However, statement string may be encoded by any
known character set by the SET NAMES statement.
The server used byte length of UTF8-encoded names to increment
the position in the query string that led to array index overrun.
