Before this fix, some tests failed due to lack of instrumentation slots in the performance schema, because the default sizing was too low. Now that more code has been instrumented, the default sizing has to be adjusted to match the current instrumentation consumption. This change: - increases the number of rwlock classes from 20 to 30, - increases the number of rwlock and mutex instances to 1 million. Both are to account for the volume of data instrumented when the innodb storage engine is used (because of the innodb buffer pool). Adjusted the test output accordingly.
