Introduce declarative function calls.
There are currently 4 different functions for sending a 9p 'Twalk'
request: v9fs_twalk(), do_walk(), do_walk_rqids() and
do_walk_expect_error(). They are all doing the same thing, just in a
slightly different way and with slightly different function arguments.
Merge those 4 functions into a single function by using a struct for
function call arguments and use designated initializers when calling
this function to turn usage into a declarative approach, which is
better readable and easier to maintain.
Also move private functions genfid(), split() and split_free() from
virtio-9p-test.c to virtio-9p-client.c.

This patch is pure refactoring, it does not change behaviour.
virtio-9p-test.c grew to 1657 lines. Let's split this file up between
actual 9p test cases vs. 9p test client, to make it easier to
concentrate on the actual 9p tests.
Move the 9p test client code to a new unit virtio-9p-client.c, which
are basically all functions and types prefixed with v9fs_* already.
Note that some client wrapper functions (do_*) are preserved in
virtio-9p-test.c, simply because these wrapper functions are going to
be wiped with subsequent patches anyway.
As the global QGuestAllocator variable is moved to virtio-9p-client.c,
add a new function v9fs_set_allocator() to be used by virtio-9p-test.c
instead of fiddling with a global variable across units and libraries.

Up to now the virt-machine node contains a virtio-mmio node.
However no driver produces any PCI interface node. Hence, PCI
tests cannot be run with aarch64 binary.
Add a GPEX driver node that produces a pci interface node. This latter
then can be consumed by all the pci tests. One of the first motivation
was to be able to run the virtio-iommu-pci tests.
We still face an issue with pci hotplug tests as hotplug cannot happen
on the pcie root bus and require a generic root port. This will be
addressed later on.
We force cpu=max along with aarch64/virt machine as some PCI tests
require high MMIO regions to be available.

At the moment the IO space limit is hardcoded to
QPCI_PIO_LIMIT = 0x10000. When accesses are performed to a bar,
the base address of this latter is compared against the limit
to decide whether we perform an IO or a memory access.
On ARM, we cannot keep this PIO limit as the arm-virt machine
uses [0x3eff0000, 0x3f000000 ] for the IO space map and we
are mandated to allocate at 0x0.
Add a new flag in QPCIBar indicating whether it is an IO bar
or a memory bar. This flag is set on QPCIBar allocation and
provisionned based on the BAR configuration. Then the new flag
is used in access functions and in iomap() function.

Eric noticed while attempting to enable the vhost-user-blk-test for
Aarch64 that that things didn't work unless he put in a dummy
guest_malloc() at the start of the test. Without it
qvirtio_wait_used_elem() would assert when it reads a junk value for
idx resulting in:
qvirtqueue_get_buf: idx:2401 last_idx:0
qvirtqueue_get_buf: 0x7ffcb6d3fe74, (nil)
qvirtio_wait_used_elem: 3000000/0
ERROR:../../tests/qtest/libqos/virtio.c:226:qvirtio_wait_used_elem: assertion failed (got_desc_idx == desc_idx): (50331648 == 0)
Bail out! ERROR:../../tests/qtest/libqos/virtio.c:226:qvirtio_wait_used_elem: assertion failed (got_desc_idx == desc_idx): (50331648 == 0)
What was actually happening is the guest_malloc() effectively pushed
the allocation of the vring into the next page which just happened to
have clear memory. After much tedious tracing of the code I could see
that qvring_init() does attempt initialise a bunch of the vring
structures but skips the vring->used.idx value. It is probably not
wise to assume guest memory is zeroed anyway. Once the ring is
properly initialised the hack is no longer needed to get things
working.

One less qemu-specific macro. It also helps to make some headers/units
only depend on glib, and thus moved in standalone projects eventually.

It is recommended to use g_autofree or g_autoptr as it reduces
the odds of introducing memory leaks in future changes.

local_test_path is allocated in virtio_9p_create_local_test_dir() to hold the path
of the temporary directory. It should be freed in virtio_9p_remove_local_test_dir()
when the temporary directory is removed. Clarify the lifecycle of local_test_path
while here.

The 9p test cases use mkdtemp() to create a temporary directory for
running the 'local' 9p tests with real files/dirs. Unlike mktemp()
which only generates a unique file name, mkdtemp() also creates the
directory, therefore the subsequent mkdir() was wrong and caused
errors on some systems.

Devices might not always be compiled into the QEMU target binaries.
We already have the libqos framework that is good for handling such
situations, but some of the qtests are not a real good fit for the
libqos framework. Let's add a qtest_has_device() function for such
tests instead.

Per https://discourse.gnome.org/t/port-your-module-from-g-memdup-to-g-memdup2-now/5538
The old API took the size of the memory to duplicate as a guint,
whereas most memory functions take memory sizes as a gsize. This
made it easy to accidentally pass a gsize to g_memdup(). For large
values, that would lead to a silent truncation of the size from 64
to 32 bits, and result in a heap area being returned which is
significantly smaller than what the caller expects. This can likely
be exploited in various modules to cause a heap buffer overflow.
Replace g_memdup() by the safer g_memdup2() wrapper.
