In our documentation, we use a mix of "$QEMU", "qemu-system-i386" and
"qemu-system-x86_64" when we give examples to the users how to run
QEMU. Some more consistency would be good here. Also some distributions
use different names for the QEMU binary (e.g. "qemu-kvm" in RHEL), so
providing more flexibility here would also be good. Thus let's define
some variables for the names of the QEMU command and use those in the
documentation instead: @value{qemu_system} for generic examples, and
@value{qemu_system_x86} for examples that only work with the x86
binaries.

Tests that require global_qtest or the related wrapper functions now
use the libqtest-single.h header that is dedicated for everything
related to global_qtest. The core libqtest.c and libqtest.h files are
now completely indepedent from global_qtest, so that the core library
is now not depending on a global state anymore.

We want libqtest.h to become completely independent from global_qtest
(so that the wrapper functions are not used by accident anymore). As
a first step, move the wrapper functions into a separate header file.

The new header is only included from libqtest.h for now, so that there
is no difference to the users of libqtest.h yet. In the next patch, we
will switch this, so that the users of the global_qtest-related
functions will be using libqtest-single.h directly and libqtest.h
becomes completely independent of this.

Library functions should not rely on functions that require global_qtest
(since they might get used in tests that deal with multiple states).
Commit 1999a70a ("Make generic virtio code independent from
global_qtest") already tried to clean the libqos virtio code, but I
missed to replace the clock_step() function. Thus change it now to
qtest_clock_step() instead.
The logic of the qvirtio_wait_config_isr() function is now pushed
to the virtio-mmio.c and virtio-pci.c files instead, since we can
get the QTestState here easily.

libqos library functions should never depend on functions (like memread(),
memwrite() or clock_step()) that require global_qtest to be set, since
library functions might get used in qtests that track multiple states, too.
Thus let's replace the global_qtest-related functions with their independent
counterparts.

The migration tests deal with multiple test states, so we really should
not use functions here that rely on the single global_qtest variable.
Switch from qtest_start() to qtest_init() to make sure that global_qtest
is not set anymore. This also revealed a regression in the migrate()
function: It has once been converted to use the qtest_qmp() function,
but commit b5bbd3f3 ("Clean up string interpolation into QMP,

VHOST_USER_PROTOCOL_F_SLAVE_SEND_FD is defined to 10, but the

in which case the test would always be false, but nevertheless
the code seems wrong.
