Subject: Fixed bug in wait_for_update() that I had introduced. Changed option
 variables to my_bool (to avoid bugs in my_getopt()) Added new thread specific
 mutex LOCK_delete to be able to free LOCK_thread_count early. Changed usage
 of LOCK_thread_count -> LOCK_status for statistics variables

libmysqld/lib_sql.cc:
  Removed not needed LOCK
mysql-test/mysql-test-run.sh:
  Log name of running test
mysql-test/r/rpl_sporadic_master.result:
  Cleaned up test
mysql-test/t/rpl_sporadic_master.test:
  cleaned up test
sql/log.cc:
  Cleanup.
  Fixed bug in wait_for_update() that I had introduced.
sql/mini_client.cc:
  Indentation changes.
sql/mysql_priv.h:
  Changed option variables to my_bool.
sql/mysqld.cc:
  Changed option variables to my_bool.
  Removed not used LOCK_server_id
  Minor code cleanups.
sql/repl_failsafe.cc:
  Minor code cleanups
sql/slave.cc:
  Minor code cleanups.
  Fixed usage of wait_for_update().
sql/slave.h:
  Changed option variables to my_bool.
sql/sql_class.cc:
  Added new thread specific mutex LOCK_delete to be able to free LOCK_thread_count early
sql/sql_class.h:
  Added new thread specific mutex LOCK_delete to be able to free LOCK_thread_count early
sql/sql_insert.cc:
  Do broadcast after unlock()
sql/sql_parse.cc:
  Removed not needed LOCK
  Changed usage of LOCK_thread_count -> LOCK_status for statistics variables
  Changed killing of threads to not lock LOCK_thread_count for long.
sql/sql_repl.cc:
  Changed options variables to my_bool
  Fixed usage of wait_for_update()
  Fixed loop to kill slaves to not lock LOCK_thread_count for long.
  Code optimization.
sql/sql_repl.h:
  bool -> my_bool
  Fixed KICK_SLAVE to use LOCK_delete
