Fix for bug#49465: valgrind warnings and incorrect live checksum...
Problem: inserting a record we don't set unused null bits in the record buffer if no default field values used. That may lead to wrong live checksum calculation. Fix: set unused null bits in the record buffer in such cases. mysql-test/r/myisam.result: Fix for bug#49465: valgrind warnings and incorrect live checksum... - test result. mysql-test/t/myisam.test: Fix for bug#49465: valgrind warnings and incorrect live checksum... - test case. sql/sql_insert.cc: Fix for bug#49465: valgrind warnings and incorrect live checksum... - set unused null bits to 1 in the record buffer in case we don't call restore_record() before a fill_record() call (when no default values used).
