Deadlock could happen if there are delayed insert + flush tables + alter table
running concurrently.
This is fixed by removing a redundant mutex lock when killing a delayed thread.

Removed redundant delayed thread mutex lock, that could result in a deadlock.
LOCK_delayed_insert is sufficient to be sure that no other thread frees delayed

Note: bug#21726 does not directly apply to 4.1, as it doesn't have stored
procedures. However, 4.1 had some bugs that were fixed in 5.0 by the
patch for bug#21726, and this patch is a backport of those fixes.
Namely, in 4.1 it fixes:
- LAST_INSERT_ID(expr) didn't return value of expr (4.1 specific).
- LAST_INSERT_ID() could return the value generated by current
statement if the call happens after the generation, like in
CREATE TABLE t1 (i INT AUTO_INCREMENT PRIMARY KEY, j INT);
INSERT INTO t1 VALUES (NULL, 0), (NULL, LAST_INSERT_ID());
- Redundant binary log LAST_INSERT_ID_EVENTs could be generated.
mysql-test/r/rpl_insert_id.result:
Add result for bug#21726: Incorrect result with multiple invocations
of LAST_INSERT_ID.
mysql-test/t/rpl_insert_id.test:
Add test case for bug#21726: Incorrect result with multiple invocations
of LAST_INSERT_ID.
sql/item_func.cc:
Add implementation of Item_func_last_insert_id::fix_fields(), where we
set THD::last_insert_id_used when statement calls LAST_INSERT_ID().
In Item_func_last_insert_id::val_int(), return THD::current_insert_id
if called like LAST_INSERT_ID(), otherwise return value of argument if
called like LAST_INSERT_ID(expr).
sql/item_func.h:
Add declaration of Item_func_last_insert_id::fix_fields().
sql/log_event.cc:
Do not set THD::last_insert_id_used on LAST_INSERT_ID_EVENT. Though we
know the statement will call LAST_INSERT_ID(), it wasn't called yet.
sql/set_var.cc:
In sys_var_last_insert_id::value_ptr(), set THD::last_insert_id_used,
and return THD::current_insert_id for @@LAST_INSERT_ID.
sql/sql_class.h:
Update comments.
Remove THD::insert_id(), as it has lost its purpose now.
sql/sql_insert.cc:
Now it is OK to read THD::last_insert_id directly.
sql/sql_load.cc:
Now it is OK to read THD::last_insert_id directly.
sql/sql_parse.cc:
In mysql_execute_command(), remember THD::last_insert_id (first
generated value of the previous statement) in THD::current_insert_id,
which then will be returned for LAST_INSERT_ID() and @@LAST_INSERT_ID.
sql/sql_select.cc:
If "IS NULL" is replaced with "= <LAST_INSERT_ID>", use right value,
which is THD::current_insert_id, and also set THD::last_insert_id_used
to issue binary log LAST_INSERT_ID_EVENT.
sql/sql_update.cc:
Now it is OK to read THD::last_insert_id directly.
tests/mysql_client_test.c:
Add test case for bug#21726: Incorrect result with multiple invocations
of LAST_INSERT_ID.

BUG#20265 (Replication of CREATE-SELECT does not work correctly):
Fixing bug by making binary log handle statement transactions.
The binary log transaction cache can now be truncated to remove
events inserted during this statement or transaction. Also, the
binary log participate in XA transaction handling, although not
as a full 2pc resource.
mysql-test/r/binlog_row_mix_innodb_myisam.result:
Result change
sql/log.cc:
Making change to binlog_end_trans() to support that it can be called
for statement transactions as well.
sql/sql_class.h:
Adding function THD::binlog_start_trans_and_stmt() to start a real transaction
(if necessary) and also a statement transaction.
sql/sql_insert.cc:
I had forgotten to delete this line (it was already disabled using //;
this line was not needed because we do the empty() every time
we write to the binlog (in MYSQL_LOG::write());
t/binlog_stm_binlog.test already tests that the empty() indeed happens
for INSERT DELAYED.

Changes to use the statement transactions that the binary log now can handle.

Non-upper-level INSERTs (the ones in the body of stored procedure,
stored function, or trigger) into a table that have AUTO_INCREMENT
column didn't affected the result of LAST_INSERT_ID() on this level.
The problem was introduced with the fix of bug 6880, which in turn was
introduced with the fix of bug 3117, where current insert_id value was
remembered on the first call to LAST_INSERT_ID() (bug 3117) and was
returned from that function until it was reset before the next
_upper-level_ statement (bug 6880).
The fix for bug#21726 brings back the behaviour of version 4.0, and
implements the following: remember insert_id value at the beginning
of the statement or expression (which at that point equals to
the first insert_id value generated by the previous statement), and
return that remembered value from LAST_INSERT_ID() or @@LAST_INSERT_ID.
Thus, the value returned by LAST_INSERT_ID() is not affected by values
generated by current statement, nor by LAST_INSERT_ID(expr) calls in
this statement.
Version 5.1 does not have this bug (it was fixed by WL 3146).
mysql-test/r/rpl_insert_id.result:

sql/item_func.cc:
Add implementation of Item_func_last_insert_id::fix_fields(), where we
remember in THD::current_insert_id the first value generated during
execution of the previous statement, which is returned then from
Item_func_last_insert_id::val_int().
sql/item_func.h:
Add declaration of Item_func_last_insert_id::fix_fields().

In sys_var_last_insert_id::value_ptr() remember in
THD::current_insert_id the first value generated during execution of the
previous statement, and return this value for @@LAST_INSERT_ID.
sql/sql_class.cc:
Reset THD::last_insert_id_used after each statement execution.
sql/sql_class.h:
Rather then remember current insert_id value on first invocation of
THD::insert_id(), remember it in Item_func_last_insert_id::fix_fields(),
sys_var_last_insert_id::value_ptr(), or mysql_execute_command().
Remove THD::insert_id(), as it lost its value now.
sql/sql_insert.cc:
THD::insert_id() is removed, use THD::last_insert_id directly.
sql/sql_load.cc:
THD::insert_id() is removed, using THD::last_insert_id directly is OK.
sql/sql_parse.cc:
Remember in THD::current_insert_id first generated insert id value of
the previous statement in mysql_execute_command().
No need to reset THD::last_insert_id_used in
mysql_reset_thd_for_next_command(), it will be reset after each
statement.
sql/sql_select.cc:
If "IS NULL" is replaced with "= <LAST_INSERT_ID>", use right value,
which is THD::current_insert_id, and also set THD::last_insert_id_used
to issue binary log LAST_INSERT_ID_EVENT.
sql/sql_update.cc:
THD::insert_id() is removed, use THD::last_insert_id directly.
tests/mysql_client_test.c:

Bug#20627 - INSERT DELAYED does not honour auto_increment_* variables
INSERT DELAYED ignored an explicitly set INSERT_ID and session
specific auto_increment_* variables.
The problem was that the inserts are done by a system thread,
which does not have access to the session variables of the user
thread.
On a proposal of Guilhem I fixed it so that the variables are
copied to the data structure for every delayed row. The system
thread sets its session variables from these values.
