Added innodb_locks_unsafe_for_binlog option. This option turns off Innodb

  next-key locking. Using this option the locks InnoDB sets on index 
  records do not affect the ``gap'' before that index record. Thus, this option
  allows phantom problem.


innobase/include/srv0srv.h:
  Added srv_locks_unsafe_for_binlog for innodb_locks_unsafe_for_binlog option.
innobase/row/row0sel.c:
  If innodb_locks_unsafe_for_binlog option is used, we lock only the record, i.e. 
  next-key locking is not used. Therefore, setting lock to the index record
  do not affect the ``gap'' before that index record. Thus, this option
  allows phantom problem, because concurrent insert operations are allowed inside 
  the select range.
innobase/srv/srv0srv.c:
  Added srv_locks_unsafe_for_binlog for innodb_locks_unsafe_for_binlog option.
sql/ha_innodb.cc:
  Added innobase_locks_unsafe_for_binlog and srv_locks_unsafe_for_binlog for 
  innodb_locks_unsafe_for_binlog option.
sql/ha_innodb.h:
  Added innobase_locks_unsafe_for_binlog for innodb_locks_unsafe_for_binlog option.
sql/mysqld.cc:
  Added OPT_INNODB_LOCKS_UNSAFE_FOR_BINLOG, innobase_locks_unsafe_for_binlog for
  innodb_locks_unsafe_for_binlog option.
sql/set_var.cc:
  Added innodb_locks_unsafe_for_binlog and innobase_locks_unsafe_for_binlog for
  innodb_locks_unsafe_for_binlog option.
