Bug#11752707-SLAVE CRASHES IF RBR HAS AS DESTINATION A VIEW

RATHER THAN A TABLE

Problem: In RBR, If a table is converted into a view at slave,
(i.e., "drop table 'object1'" & "create view 'object1'"), then any
DML operations on the table at master are causing crash at slave.

Analysis: Slave prepares tables to be opened for DML list when it
receives Table_map_log_event(s). And the same list will be sent to
open_table function. Open_table logic assumes that if the list
contains a view object, it also contains "select_lex" object of
that view. In the above special case, the table object does not
contain 'select_lex' as it is base table at master. Since it
is a view at slave, open_table logic goes to 'mysql_make_view()'
function which assumes that 'select_lex' exists for the object.

Fix: While preparing 'tables to be opened' list, we should make 
sure that table required type is 'base table'. If it is not 
base table while opening the object, mysql_make_view will throw an 
error similar to 'object is not a base table' 

sql/log_event.cc:
  Restrict that all table_map_log_event's objects should be 
  base tables @ slave also.
