[Qemu-devel] [PULL for-2.0 01/16] Revert "qtest: Fix crash if SIGABRT during qtest_init()"

["Andreas Färber" <afaerber@suse.de>]

From: Stefan Hajnoczi <stefanha@redhat.com>

It turns out there are test cases that use multiple libqtest instances.
We cannot use a global qtest instance in the SIGABRT handler.

This reverts commit cb201b4872f16dfbce63f8648b2584631e2e965f.
