A NDOB bit set to one specifies that the disk shall not transfer data
from the data-out buffer and shall process the command as if the data-out
buffer contained user data set to all zeroes.

Drop one more client of global_qtest by teaching all remaining
libqos stragglers to pass in an explicit QTestState. Change the
setting of global_qtest from being implicit in libqos' call to
qtest_start() to instead be explicit in all clients that are
still relying on global_qtest.
Note that qmp_execute() can be greatly simplified in the process,
and that we also get rid of interpolation of a JSON string into a
temporary variable when qtest_qmp() can do it more reliably.

When a 9p request is flushed (ie, cancelled) by the guest, the device
is expected to simply mark the request as used, without sending a 9p
reply (ie, without writing anything into the used buffer).
To be able to test this, we need access to the length written by the
device into the used descriptor. This patch adds a uint32_t * argument
to qvirtqueue_get_buf() and qvirtio_wait_used_elem() for this purpose.
All existing users are updated accordingly.

A lot of tests provide code for adding and removing a device via the
device_add and device_del QMP commands. Maintaining this code in so many
places is cumbersome and error-prone (some of the code parts check the
responses for device deletion in an incorrect way, for example, we've got
to deal with both, error code and DEVICE_DEL event here). So let's provide
some proper generic functions for adding and removing a device instead.
The code for correctly unplugging a device has been taken from a patch
from Peter Xu.

The 'addr' parameter to qvirtio_config_read*() doesn't have a consistent
meaning: when using the virtio-pci versions, it's a full PCI space address,
but for virtio-mmio, it's an offset from the device's base mmio address.
This means that the callers need to do different things to calculate the
addresses in the two cases, which rather defeats the purpose of function
pointer backends.
All the current users of these functions are using them to retrieve
variables from the device specific portion of the virtio config space.
So, this patch alters the semantics to always be an offset into that
device specific config area.

This patch replaces calls to qtest_start() and qtest_end() by
calls to qtest_pc_boot() and qtest_shutdown().
This allows to initialize memory allocator and PCI interface
functions. This will ease to enable virtio tests on other
architectures by only adding a specific qtest_XXX_boot() (like
qtest_spapr_boot()).

qvirtqueue_setup() allocates the vring and virtqueue state. So far
there has been no function to free it. Callers have been using
guest_free() for the vring but forgot to free the QVirtQueue state.
