Drop one more client of global_qtest by teaching all remaining libqos stragglers to pass in an explicit QTestState. Change the setting of global_qtest from being implicit in libqos' call to qtest_start() to instead be explicit in all clients that are still relying on global_qtest. Note that qmp_execute() can be greatly simplified in the process, and that we also get rid of interpolation of a JSON string into a temporary variable when qtest_qmp() can do it more reliably.
