Patch to eliminate some valgrind warnings in debug printout code.

Browse source 
(originally from Mats)


sql/rpl_rli.cc:
  Adding variable to mark an instance of Relay_log_info as fake.
sql/rpl_rli.h:
  Adding variable to mark an instance of Relay_log_info as fake.
sql/slave.cc:
  Not printing debug information if we are working with a fake
  instance of Relay_log_info. This because the result of calling
  update is nonsense, and trying to print it generates valgrind
  warnings.
sql/sql_binlog.cc:
  Marking newly created instance of Relay_log_info as a fake instance.
