Fix for bug #29928: INSERT ... VALUES(connection_id(), ...) incorrect

Browse Source 
restores from mysqlbinlog out

Problem: using "mysqlbinlog | mysql" for recoveries the connection_id() 
result may differ from what was used when issuing the statement.

Fix: if there is a connection_id() in a statement, write to binlog
SET pseudo_thread_id= XXX; before it and use the value later on.
