Replaced Unix calls with mysql-test-run's built-in functions / SQL manipulation where possible.
Replaced error codes with error names as well.
Disabled two tests on Windows due to more complex Unix command usage
See Bug#41307, Bug#41308
Rename mix_innodb_myisam_binlog-master.opt; when the test was moved to
separate stm/row test cases, the .opt were not moved along with it,
causing a 60-second test duration because of default lock timeout :-(
