As a general rule, we prefer avoiding implicit global state because it makes code harder to safely copy and paste without thinking about the global state. Adjust the helper code to use explicit state instead, and update all callers. bios-tables-test no longer depends on global_qtest, now that it passes explicit state through the testsuite data; an assert proves this fact (although we will get rid of it later, once global_qtest is gone).
