Update the .acpipcihp blob variant for the aarch64 'virt' machine. Since
this is a new blob, the diff is large and not particularly useful, so
below is the diff against the base DSDT blob with ACPI PCI off.
Main changes include:
a) The _OSC method, which now allows the platform to control PCIe
ACPI PCI hotplug is now turned on by default so we need to change the
existing tests to keep it off. However, even setting the ACPI PCI
hotplug off in the existing tests, there will be changes in the ACPI
tables because the _OSC method was modified, hence in the next patch of
this series the blobs
This series updates the existing ACPI tests to work with the new support
for ACPI PCI hotplug on aarch64, which is now enabled by default in the
'virt' machine. Because ACPI PCI hotplug is now enabled by default it's
necessary to disable it (acpi-pcihp=off) for the existing tests, because

In a recent discussion, Phil Dennis-Jordan pointed out a quirk in
QemuEvent destruction due to futex-like abstraction, which prevented
the usage of QemuEvent in new and existing code[1]. With some more
thoughts after this discussion, I also found other problem and room
of improvement in futex usage
qemu-thread used to abstract pthread primitives into futex for the
QemuEvent implementation of POSIX systems other than Linux. However,
this abstraction has one key difference: unlike futex, pthread
primitives require an explicit destruction, and it must be ordered after
wait and wake operations.
pause_event can utilize qemu_event_reset() to discard events.

The buffer size calculated by AUD_get_buffer_size_out() is often
