"If 2 master threads with same-name temp table, slave makes bad binlog"
and (two birds with one stone) for
BUG#1240 "slave of slave breaks when STOP SLAVE was issud on parent slave
and temp tables".

Here is the design change:
in a slave running with --log-slave-updates, events are now logged with the
thread id they had on the master. So no more id conflicts between master threads,
but introduces id conflicts between one master thread and one normal 
client thread connected to the slave. This is solved by storing the server id
in the temp table's name.

New test which requires mysql-test-run to be run with --manager,
otherwise it will be skipped.

Undoing a Monty's change (hum, a chill runs down my spine ;) which was
"Cleanup temporary tables when slave ends" in ChangeSet 1.1572.1.1.


mysql-test/mysql-test-run.sh:
  One new test which needs more than one slave so must be hardcoded in mysql-test-run.sh.
sql/log_event.cc:
  The event needs to carry a slave_proxy_id (which is set at event's creation
  and used at event's logging).
  This is used for events created by ::exec_event() in the slave SQL thread:
  now we want to log these events with the thread id they had on the master.
  This is so that several same-name temp tables simultaneously created on
  the master end up with not the same thread id in the slave's binlog.
sql/log_event.h:
  Query and Load need to carry a slave_proxy_id, like they carried a thread_id
  (to replicate temp tables well).
sql/slave.cc:
  Do not free temp tables in the slave SQL thread. Or they will be lost when
  one does STOP SLAVE / START SLAVE.
  We even save them in rli->save_temporary_tables and set thd->temporary_tables=0
  to prevent them to be freed.
sql/sql_base.cc:
  Put the server id in the table cache key name for temp tables
  (we already put the slave_proxy_id, but we also need the server id
  in case normal clients (not slave threads) are using temp tables
  on the slave).
sql/unireg.h:
  4 more bytes, to store the server id.

Make mysqlbinlog prompt for the password if
mysqlbinlog -p
instead of printing the usage().
This makes mysqlbinlog behave like other clients.
This new code was almost copied from mysqldump.
Note that before, one could use
  mysqlbinlog -p pass
and now one must use
  mysqlbinlog -ppass
(putting a space will ask for the password).

sql/sql_select.cc:
  back to the bug #1274:
  the following query
  EXPLAIN SELECT SQL_CALC_FOUND_ROWS race_name 
  FROM races WHERE race_name LIKE '%Madison%' ORDER BY race_date DESC LIMIT 0,100
  
  +-------+------+---------------+------+---------+------+--------+-----------------------------+
  | table | type | possible_keys | key  | key_len | ref  | rows   | Extra                       |
  +-------+------+---------------+------+---------+------+--------+-----------------------------+
  | races | ALL  | NULL          | NULL |    NULL | NULL | 505821 | Using where; Using filesort |
  +-------+------+---------------+------+---------+------+--------+-----------------------------+
  
  The query returns no rows.
  
  There are two problems with it: 
  - wrong access plan is chosed  (sequential index scan in reverse order,
  which is VERY SLOW in case of MyISAM table + packed keys)
  It's wrong, because it doesn't take into account that SQL_CALC_FOUND_ROWS 
  is present, in other words, is based on assumtion that LIMIT
  clause decrease number of rows to access significantly, which is
  not true as all rows are accessed.
  - the access plan is not shown in the EXPLAIN (bug #1560). I'm not
  fixing it here
