[Qemu-devel] [PULL 01/48] qtest: don't report signals if qtest driver enabled

["Andreas Färber" <afaerber@suse.de>]

From: "Michael S. Tsirkin" <mst@redhat.com>

qtest driver always uses signals to kill qemu
no need to report it, whatever the accelerator state.

Add API to detect qtest driver, and suppress reporting
signals in this case.
