The tulip networking card emulation has an OOB issue in
'tulip_copy_tx_buffers' when the guest provide malformed descriptor.
This test will trigger a ASAN heap overflow crash. To trigger this
issue we can construct the data as following:
1. construct a 'tulip_descriptor'. Its control is set to
'0x7ff | 0x7ff << 11', this will make the 'tulip_copy_tx_buffers's
'len1' and 'len2' to 0x7ff(2047). So 'len1+len2' will overflow
'TULIPState's 'tx_frame' field. This descriptor's 'buf_addr1' and
'buf_addr2' should set to a guest address.
2. write this descriptor to tulip device's CSR4 register. This will
set the 'TULIPState's 'current_tx_desc' field.
3. write 'CSR6_ST' to tulip device's CSR6 register. This will trigger
'tulip_xmit_list_update' and finally calls 'tulip_copy_tx_buffers'.
Following shows the backtrack of crash:

In commit 6f8bbb374b we enabled building with the gcrypt library
on the the Debian 'x86 host', which was based on Debian Stretch.
Later in commit 698a71edbe we upgraded the Debian base image to
Buster.
Apparently Debian Stretch was listing gcrypt as a QEMU dependency,
but this is not the case anymore in Buster, so we need to install
it manually (it it not listed by 'apt-get -s build-dep qemu' in
the common debian10.docker anymore). This fixes:

Test that qemu-img check reports the number of leaks and corruptions
fixed in its JSON report (after a successful run).
While touching the _unsupported_imgopts line, adjust the note on why
data_file does not work with this test: The current comment sounds a bit
like it is a mistake for qemu-img check not to check external data
files' refcounts. But there are no such refcounts, so it is no mistake.
Just say that qemu-img check does not do much for external data files,
and this is why this test does not work with them.

As the feature name table can be quite large (over 9k if all 64 bits
of all three feature fields have names; a mere 8 features leaves only
8 bytes for a backing file name in a 512-byte cluster), it is unwise
to emit this optional header in images with small cluster sizes.
Update iotest 036 to skip running on small cluster sizes; meanwhile,
note that iotest 061 never passed on alternative cluster sizes
(however, I limited this patch to tests with output affected by adding
feature names, rather than auditing for other tests that are not
robust to alternative cluster sizes).

Per David Gilbert, "it could just be the writing is slow on s390
and the migration thread fast; in which case the autocomplete
wouldn't be needed. Perhaps we just need to reduce the bandwidth
limit."
Tuning the threshold by reducing the initial bandwidth makes the
autoconverge test pass.

Firstly, _next_dirty_area is for scenarios when we may contiguously
search for next dirty area inside some limited region, so it is more
comfortable to specify "end" which should not be recalculated on each
iteration.
Secondly, let's add a possibility to limit resulting area size, not
limiting searching area. This will be used in NBD code in further
commit. (Note that now bdrv_dirty_bitmap_next_dirty_area is unused)

We are going to introduce bdrv_dirty_bitmap_next_dirty so that same
variable may be used to store its return value and to be its parameter,
so it would int64_t.
Similarly, we are going to refactor hbitmap_next_dirty_area to use
hbitmap_next_dirty together with hbitmap_next_zero, therefore we want
hbitmap_next_zero parameter type to be int64_t too.
So, for convenience update all parameters of *_next_zero and
*_next_dirty_area to be int64_t.

Podman users will most often be using buildah to build containers.
Among the differences between "buildah bud|build-using-dockerfile" and
a traditional "docker build" is that buildah does not run a container
during build.
To the best of my knowledge and experiments, this means that runtime
variables, such as ENV from one base image will not propagate into
another. The end result is that the location for the cross compiler
binaries, defined in the base "qemu/debian9-mxe" image, are not passed
through this image. Consequently, the cross compilers are not on PATH
and the build fails.

The newly introduced "boot linux" tests make use of Linux images that
are larger than usual, and fall into what Avocado calls "vmimages",
and can be referred to by name, version and architecture.
The images can be downloaded automatically during the test. But, to
make for more reliable test results, this introduces a target that
will download the vmimages for the architectures that have been
configured and are available for the currently used distro (Fedora
31).

This acceptance test, validates that a full blown Linux guest can
successfully boot in QEMU. In this specific case, the guest chosen is
Fedora version 31.
* x86_64, pc-i440fx and pc-q35 machine types, with TCG and KVM as
accelerators
* aarch64 and virt machine type, with TCG and KVM as accelerators
* ppc64 and pseries machine type with TCG as accelerator
* s390x and s390-ccw-virtio machine type with TCG as accelerator
The Avocado vmimage utils library is used to download and cache the
Linux guest images, and from those images a snapshot image is created
and given to QEMU. If a qemu-img binary is available in the build
directory, it's used to create the snapshot image, so that matching
qemu-system-* and qemu-img are used in the same test run. If qemu-img
is not available in the build tree, one is attempted to be found
installed system-wide (in the $PATH). If qemu-img is not found in the
build dir or in the $PATH, the test is canceled.
The method for checking the successful boot is based on "cloudinit"
and its "phone home" feature. The guest is given an ISO image with
the location of the phone home server, and the information to post
(the instance ID). Upon receiving the correct information, from the
guest, the test is considered to have PASSed.
This test is currently limited to user mode networking only, and
instructs the guest to connect to the "router" address that is hard
coded in QEMU.
To create the cloudinit ISO image that will be used to configure the
guest, the pycdlib library is also required and has been added as
requirement to the virtual environment created by "check-venv".
The console output is read by a separate thread, by means of the
Avocado datadrainer utility module.

Some tests may benefit from using resources from a build directory.
This introduces three variables that can help tests find resources in
those directories.
First, a BUILD_DIR is assumed to exist, given that the primary form of
running the acceptance tests is from a build directory (which may or
may not be the same as the source tree, that is, the SOURCE_DIR).
If the directory containing the acceptance tests happens to be a link
to a directory, it's assumed to it points to the source tree
(SOURCE_DIR), which is the behavior defined on the QEMU Makefiles. If
the directory containing the acceptance tests is not a link, then a
in-tree build is assumed, and the BUILD_DIR and SOURCE_DIR have the
same value.

c9d4070991 "file-posix: Add dynamic-auto-read-only QAPI feature"). In
