Fixes to eliminate valgrind warnings.
sql/rpl_record.cc: Factoring out expression and putting it in an auto variable. sql/rpl_utility.cc: Removing a check that causes compile warnings. sql/rpl_utility.h: Ensuring that there is enough memory for the metadata, to avoid reads from uninitialized memory. Initializing the memory to keep valgrind quiet.
