Bug#16084594 USER_VAR ITEM IN 'LOAD FILE QUERY' WAS NOT

Browse source 
PROPERLY QUOTED IN BINLOG FILE
Problem: In load data file query, User variables are allowed
inside "Into_list" and "Set_list". These user variables used
inside these two lists are not properly guarded with backticks
while server is writting into binlog. Hence user variable names
like a` cannot be used in this context.

Fix: Properly quote these variables while
writting into binlog
