accel/tcg: Un-inline translator_is_same_page()

Remove the single target-specific definition used in
"exec/translator.h" (TARGET_PAGE_MASK) by un-inlining
is_same_page().
Rename the method as translator_is_same_page() and

Use it in translator_use_goto_tb().

tests: Fix test-qdev-global-props on anonymous qdev realize()

test-qdev-global-props creates a few subprocesses and test things based on
qdev realize().  One thing was overlooked since the start, that anonymous
creations of qdev (then realize() the device) requires the machine object's
presence, as all these devices need to be attached to QOM tree, by default
to path "/machine/unattached".

The test didn't crash simply because container_get() has an implicit
semantic to silently create any missing container, hence what happened here
is container_get() (when running these tests) will try to create containers
at QOM path "/machine" on the fly.  That's probably unexpected by the test,
but worked like charm before.

We're going to fix device_set_realized() soon, but before that make the
test case prepared, by creating the machine object on its own.

The run_agent_once() function is already given GAState via an
argument. There's no need to access the global ga_state variable
which points to the argument anyways (thanks to

qga: skip bind mounts in fs list

The filesystem list in build_fs_mount_list should skip bind mounts.
This because we end up in locking situations when doing fsFreeze. Like
mentioned in [1] and [2].

Next to that, the build_fs_mount_list call did a fallback via
build_fs_mount_list_from_mtab if mountinfo did not exist.
There it skipped bind mounts, but this is broken for newer OS.
This as mounts does not return the path of the bind mount but the
underlying dev/partition, so S_ISDIR will never return true in
dev_major_minor call.

This patch simply checks the existing devmajor:devminor tuple in the
mounts, and if it already exists, this means we have the same devices
mounted again, a bind mount. So skip this.

Same approach is used in open-vm-tools [3].

meson.build: Disallow libnfs v6 to fix the broken macOS build

The macOS builds in our CI (and possibly other very recent distros)
are currently broken since the update to libnfs version 6 there.
That version apparently comes with a big API breakage. v5.0.3 was
the final release of the old API (see the libnfs commit here:
https://github.com/sahlberg/libnfs/commit/4379837 ).

Disallow version 6.x for now to get the broken CI job working
again. Once somebody had enough time to adapt our code in
block/nfs.c, we can revert this change again.

tests/functional: Convert the hotplug_cpu avocado test

Since we don't have ssh support in the functional test framework yet,
simply use the serial console for this test instead. It's also
sufficient to only boot into an initrd here, no need to fire up a
full-blown guest, so the test now finishes much faster.

While we're at it, also unplug the CPU now and check that it is gone
in the guest.

tests/functional: Convert the intel_iommu avocado test

Convert the intel_iommu test to the new functional framework.
This test needs some changes since we neither support the old 'LinuxTest'
class in the functional framework yet, nor a way to use SSH for running
commands in the guest. So we now directly download a Fedora kernel and
initrd and set up the serial console for executing the commands and for
looking for the results. Instead of configuring the cloud image via
cloud-init, we now simply mount the file system manually from an initrd
rescue shell.

While the old test was exercising the network with a "dnf install"
command (which is not the best option for the CI since this depends
on third party servers), the new code is now setting up a little
HTTP server in the guest and transfers a file from the guest to the
host instead.

The test should now run much faster and more reliable (since we
don't depend on the third party servers for "dnf install" anymore),
so we can also drop the @skipUnless decorator now.

a generalized 'archive_extract' that can detect the format and
delegate to the appropriate helper for extraction. This ensures
that all archive extraction code follows the same design pattern.

tests/functional: let cpio_extract accept filenames

Currently cpio_extract differs from tar_extract/zip_extract
in that it only allows a file-like object as input. Adapt it
to also support filenames.

tests/functional: move uncompress handling into new uncompress.py file

More uncompress related code will be added shortly, so having a
separate file makes more sense.

The utils.py imports the functions from archive.py, so that
existing callers don't need to be modified. This avoids
redundant code churn until later in the series when all
calls will be adapted for other reasons.

Everything in the scratch directory is automatically purged. Calling
'rmtree' again breaks the ability to optionally preserve the scratch
