In commit 81b3ddaf87 we fixed a use of uninitialized data
in read_tcnt(). However this change wasn't enough to placate
Coverity, which is not smart enough to see that if we read a
2 bit field and then handle cases 0, 1, 2 and 3 then there cannot
be a flow of execution through the switch default. Add explicit
default cases which assert that they can't be reached, which
should help silence Coverity.

Currently we give all the v7-and-up CPUs a PMU with 4 counters. This
means that we don't provide the 6 counters that are required by the
Arm BSA (Base System Architecture) specification if the CPU supports
the Virtualization extensions.
Instead of having a single PMCR_NUM_COUNTERS, make each CPU type
specify the PMCR reset value (obtained from the appropriate TRM), and
use the 'N' field of that value to define the number of counters
provided.
This means that we now supply 6 counters for Cortex-A53, A57, A72,
A15 and A9 as well as '-cpu max'; Cortex-A7 and A8 stay at 4; and
Cortex-R5 goes down to 3.
Note that because we now use the PMCR reset value of the specific
implementation, we no longer set the LC bit out of reset. This has
an UNKNOWN value out of reset for all cores with any AArch32 support,
so guest software should be setting it anyway if it wants it.

Three test cases:
(1) Adding a qcow2 (metadata) file to an existing data file, see whether
we can read the existing data through the qcow2 image.
(2) Append data to the data file, grow the qcow2 image accordingly, see
whether we can read the new data through the qcow2 image.
(3) At runtime, add a backing image to a freshly created qcow2 image
with an external data file (with data-file-raw). Reading data from
the qcow2 image must return the same result as reading data from the
data file, so everything in the backing image must be ignored.
(This did not use to be the case, because without the L2 tables
preallocated, all clusters would appear as unallocated, and so the
qcow2 driver would fall through to the backing file.)

Setting the qcow2 data-file-raw bit means that you can ignore the
qcow2 metadata when reading from the external data file. It does not
mean that you have to ignore it, though. Therefore, the data read must
be the same regardless of whether you interpret the metadata or whether
you ignore it, and thus the L1/L2 tables must all be present and give a
1:1 mapping.
This patch changes 244's output: First, the qcow2 file is larger right
after creation, because of metadata preallocation. Second, the qemu-img
map output changes: Everything that was not explicitly discarded or
zeroed is now a data area.

Max noticed that since blk_aio_pwrite_zeroes() may invoke the callback
before returning, the callbacks will never see *count == 0 and thus
never free the count variable or decrement num_formats causing a CQE to
never be posted.
Coverity (CID 1451082) also picked up on the fact that count would not
be free'ed if the namespace was of zero size.
Fix both of these issues by explicitly checking *count and finalize for
the given namespace if --(*count) is zero. Enqueing a CQE if there are
no AIOs outstanding after this case is already handled by nvme_format()
by inspecting *num_formats.

mirror_top currently shares all permissions, and takes only the WRITE
permission (if some parent has taken that permission, too).
That is wrong, though; mirror_top is a filter, so it should take
permissions like any other filter does. For example, if the parent
needs CONSISTENT_READ, we need to take that, too, and if it cannot share
the WRITE permission, we cannot share it either.
The exception is when mirror_top is used for active commit, where we
cannot take CONSISTENT_READ (because it is deliberately unshared above
the base node) and where we must share WRITE (so that it is shared for
all images in the backing chain, so the mirror job can take it for the
target BB).

This happens because the device is doing things at "instance_init" time

Since the virtio-gpu-ccw device depends on the hw-display-virtio-gpu
module, which provides the type virtio-gpu-device, packaging the
hw-display-virtio-gpu module as a separate package that may or may not
be installed along with the qemu package leads to problems. Namely if
the hw-display-virtio-gpu is absent, qemu continues to advertise
virtio-gpu-ccw, but it aborts not only when one attempts using
virtio-gpu-ccw, but also when libvirtd's capability probing tries
to instantiate the type to introspect it.
Let us thus introduce a module named hw-s390x-virtio-gpu-ccw that
is going to provide the virtio-gpu-ccw device. The hw-s390x prefix
was chosen because it is not a portable device.
With virtio-gpu-ccw built as a module, the correct way to package a
modularized qemu is to require that hw-display-virtio-gpu must be
installed whenever the module hw-s390x-virtio-gpu-ccw.

When setting up the pointer for the sigreturn stub in the return
address register (r14) we currently use the host frame address instead
of the guest frame address.
Note: This only caused problems if Qemu has been built with
--disable-pie (as it is in distros nowadays). Otherwise guest_base
defaults to 0 hiding the actual problem.

In d0f26e68a0 ("gitlab: force enable docs build in Fedora, Ubuntu,
Debian") we made sure we can build the documents on more than one
system. However we don't want to build documents all the time as it's
a waste of cycles (and energy). So lets reduce the total amount of
documentation we build while still keeping coverage of at least one
build on each supported target.

Commit f1d5516ab5 introduces a test in some iotests to check if
the machine is a s390-ccw-virtio and to select virtio-*-ccw rather
than virtio-*-pci.
We don't need that because QEMU already provides aliases to use the correct
virtio interface according to the machine type.
This patch removes all virtio-*-pci and virtio-*-ccw to use virtio-*
instead and remove get_virtio_scsi_device().
This also enables virtio-mmio devices (virtio-*-device)

Rather than checking if the machine is an s390x to use virtio-blk-ccw
instead of virtio-blk-pci, use the alias virtio-blk that is set to
the expected target.
This also enables the use of virtio-blk-device for targets without

Similarly to 5f629d943c ("s390x: fix s390 virtio aliases"),
define the virtio aliases.
This allows to start machines with virtio devices without
knowledge of the implementation type.
For instance, we can use "-device virtio-scsi" on
m68k, s390x or PC, and the device will be respectively
"virtio-scsi-device", "virtio-scsi-ccw" or "virtio-scsi-pci".
This already exists for s390x and -ccw interfaces, add them
for m68k and MMIO (-device) interfaces.

Mingw recognizes that "0x" has value 0 without setting errno, but
fails to advance endptr to the trailing garbage 'x'. This in turn
showed up in our recent testsuite additions for qemu_strtosz (commit
1657ba44b4 utils: Enhance testsuite for do_strtosz()); adjust our
remaining tests to show that we now work around this windows bug.

Our tests were not validating the return value in all cases, nor was
it guaranteeing our documented claim that 'res' is unchanged on error.
For that matter, it wasn't as thorough as the existing tests for
qemu_strtoi() and friends for proving that endptr and res are sanely
set. Enhancing the test found one case where we violated our
documentation: namely, when failing with EINVAL when endptr is NULL,
we shouldn't modify res.

FreeBSD version 12.1 is out of service now, and the task in the
Cirrus-CI is failing. Update to 12.2 to get it working again.
Unfortunately, there is a bug in libtasn1 that triggers with the
new version of Clang that is used there (see this thread for details:
https://lists.gnu.org/archive/html/qemu-devel/2021-02/msg00739.html ),
so we have to disable gnutls for now to make it work again. We can
enable it later again once libtasn1 has been fixed in FreeBSD.

Looking for they way we are using atomic functions in QEMU, we are not
using these functions with the _16 suffix anyway. Switch to the same
