[Qemu-block] [PATCH v7 1/6] iotests: allow Valgrind checking all QEMU processes

With the '-valgrind' option, let all the QEMU processes be run under the Valgrind tool. The Valgrind own parameters may be set with its environment variable VALGRIND_OPTS, e.g. $ VALGRIND_OPTS="--leak-check=yes" ./check -valgrind or they may be listed in the Valgrind checked file ./.valgrindrc or

[Qemu-block] [PATCH v7 0/6] Allow Valgrind checking all QEMU processes

In the current implementation of the QEMU bash iotests, only qemu-io processes may be run under the Valgrind with the switch '-valgrind'. Let's allow the common.rc bash script running all other QEMU processes, such as qemu-kvm, qemu-img, qemu-ndb and qemu-vxhs, under the Valgrind. v7: 01: The
