We are going to move the tests for each target into separate subdirectories.
The multiprocess test currently contains code for both, x86 and aarch64,
so it does not quite fit into this scheme. Rework the test to have a common
test class, and target specific files with a target specific class, so
that this will fit better into the new scheme.

Currently, we have one lock that is held while a test is looking for
free ports. However, we are also using different ranges for looking
for free ports nowadays (PORTS_START is based on the PID of the process),
so instead of using only one lock, we should rather use a lock per
range instead. This should help to allow running more tests in parallel.
While we're at it, also create the lock files without executable bit
(mode is 0o777 by default).

This commit fixes the asset precaching in the reverse_debugging test on
aarch64.
QemuBaseTest.main() precaches assets (kernel, rootfs, DT blobs, etc.)
that are defined in variables with the ASSET_ prefix. This works because
it ultimately calls Asset.precache_test(), which relies on introspection
to locate these variables.
If an asset variable is not named with the ASSET_ prefix, precache_test
cannot find the asset and precaching silently fails. Hence, fix the
asset precaching by fixing the asset variable name.

If you are using the Nvidia drivers and have installed new versions
of those packages but have not yet rebooted the host kernel,
attempting to use the egl-headless display will cause QEMU to fail to
start with
$ qemu-system-aarch64 -M virt -display egl-headless
qemu-system-aarch64: egl: eglInitialize failed: EGL_NOT_INITIALIZED
qemu-system-aarch64: egl: render node init failed
together with this complaint in the host kernel dmesg:
[7874777.555649] NVRM: API mismatch: the client has the version 535.247.01, but
NVRM: this kernel module has the version 535.230.02. Please
NVRM: make sure that this kernel module and all NVIDIA driver
NVRM: components have the same version.
This isn't a problem with QEMU itself, so reporting this as a test
failure is misleading. Instead skip the tests, as we already do for
various other kinds of "host system can't actually run the EGL
display" situation.

mark_unavailable_features() actively blocks usage of the feature,

qemu_rbd_get_specific_info() has at least two problems:
The first is that it issues a blocking rbd_read() call in order to probe
the encryption format for the image while querying the node. This means
that if the connection to the server goes down, not only I/O is stuck
(which is unavoidable), but query-names-block-nodes will actually make
the whole QEMU instance unresponsive. .bdrv_get_specific_info
implementations shouldn't perform blocking operations, but only return
what is already known.
The second is that the information returned isn't even correct. If the
image is already opened with encryption enabled at the RBD level, we'll
probe for "double encryption", i.e. if the encrypted data contains
another encryption header. If it doesn't (which is the normal case), we
won't return the encryption format. If it does, we return misleading
information because it looks like we're talking about the outer level
(the encryption format of the image itself) while the information is
about an encryption header in the guest data.
Fix this by storing the encryption format in BDRVRBDState when the image
is opened (and we do blocking operations anyway) and returning only the
stored information in qemu_rbd_get_specific_info().
The information we'll store is either the actual encryption format that
we enabled on the RBD level, or if the image is unencrypted, the result
of the same probing as we previously did when querying the node. Probing
image formats based on content that can be modified by the guest has
long been known as problematic, but as long as we only output it to the
user instead of making decisions based on it, it should be okay. It is
undoubtedly useful in the context of 'qemu-img info' when you're trying
to figure out which encryption options you have to use to open the
image successfully.

When the guest writes to register UEFI_VARS_REG_BUFFER_SIZE, the .write
callback `uefi_vars_write` is invoked. The function allocates a
heap buffer without zeroing the memory, leaving the buffer filled with
residual data from prior allocations. When the guest later reads from
register UEFI_VARS_REG_PIO_BUFFER_TRANSFER, the .read callback
`uefi_vars_read` returns leftover metadata or other sensitive process
memory from the previously allocated buffer, leading to an information
disclosure vulnerability.

The emulated device had let the user set whatever max transfers size
they wanted, including no limit. However the device does have an
internal limit of 1024 segments. NVMe doesn't report max segments,
though. This is implicitly inferred based on the MDTS and MPSMIN values.
IOV_MAX is currently 1024 which 4k PRPs can exceed with 2MB transfers.
Don't allow MDTS values that can exceed this, otherwise users risk
seeing "internal error" status to their otherwise protocol compliant

cpr-transfer may lose a VFIO interrupt because the KVM instance is
destroyed and recreated. If an interrupt arrives in the middle, it is
dropped. To fix, stop pending new interrupts during cpr save, and pick
up the pieces. In more detail:
Stop the VCPUs. Call kvm_irqchip_remove_irqfd_notifier_gsi --> KVM_IRQFD to
deassign the irqfd gsi that routes interrupts directly to the VCPU and KVM.
After this call, interrupts fall back to the kernel vfio_msihandler, which
writes to QEMU's kvm_interrupt eventfd. CPR already preserves that
eventfd. When the route is re-established in new QEMU, the kernel tests
the eventfd and injects an interrupt to KVM if necessary.
Deassign INTx in a similar manner. For both MSI and INTx, remove the
eventfd handler so old QEMU does not consume an event.
If an interrupt was already pended to KVM prior to the completion of
kvm_irqchip_remove_irqfd_notifier_gsi, it will be recovered by the
subsequent call to cpu_synchronize_all_states, which pulls KVM interrupt
state to userland prior to saving it in vmstate.
