qemu-io: add option to enable tracing
It can be useful to enable QEMU tracing when trying out block layer
interfaces via qemu-io. Tracing can be enabled using the new -T FILE
option where the given file contains a list of trace events to enable
(just like the qemu --trace events=FILE option).
$ echo qemu_vfree >my-events
$ ./qemu-io -T my-events ...Remember to use ./configure --enable-trace-backend=BACKEND when building
qemu-io.
