BUG#11754117 incorrect logging of INSERT into auto-increment

BUG#11761686 insert_id event is not filtered.
  
Two issues are covered.
  
INSERT into autoincrement field which is not the first part in the composed primary key 
is unsafe by autoincrement logging design. The case is specific to MyISAM engine
because Innodb does not allow such table definition.
  
However no warnings and row-format logging in the MIXED mode was done, and
that is fixed.
  
Int-, Rand-, User-var log-events were not filtered along with their parent
query that made possible them to screw up execution context of the following
query.
  
Fixed with deferring their execution until the parent query.

  results updated.
mysql-test/suite/rpl/t/rpl_auto_increment_bug45679.test:
  regression test for BUG#11754117-45670 is added.
mysql-test/suite/rpl/t/rpl_filter_tables_not_exist.test:
  regression test for filtering issue of BUG#11754117 - 45670 is added.
sql/log_event.cc:
  Logics are added for deferring and executing events associated 
  with the Query event.
sql/log_event.h:
  Interface to deferred events batch execution is added.
sql/rpl_rli.cc:
  initialization for new RLI members is added.
sql/rpl_rli.h:
  New members to RLI are added to facilitate deferred events gathering
  and execution control;
  two general character RLI cleanup methods are constructed.
sql/rpl_utility.cc:
  Deferred_log_events methods are difined.
sql/rpl_utility.h:
  A new class Deferred_log_events is defined to implement
  IRU events gathering, execution and cleanup.
sql/slave.cc:
  Necessary changes to initialize `rli->deferred_events' and prevent
  deferred event deletion in the main read-exec branch.
sql/sql_base.cc:
  A new safe-check function for multi-part pk with auto-increment is defined
  and deployed in lock_tables().
sql/sql_class.cc:
  Initialization for a new member and replication cleanups are added
  to THD class.
sql/sql_class.h:
  THD class receives a new member to hold a specific execution
  context for slave applier.
sql/sql_parse.cc:
