Currently we need to test both device tree and ACPI on AArch64. As
the number of ACPI test cases is gradually increasing and expected
to increase in the future, it is better to extract all ACPI test
cases on AArch64 to a single module.

Current AArch64 power button is only for device tree using a PL061
GPIO controller device. Since AArch64 now supports ACPI, this
commit extend the power button on AArch64 to:
- Using GED for ACPI+UEFI boot.
- Using PL061 for device tree boot.

This message only occurs sporadically and so it should be included at
info!() level. Enhance the output to also include the BAR number.

These statements are useful for understanding the cause of reset or
shutdown of the VM and are not spammy so should be included at info!()
level.

This patch adds a separate function to perform common numa checks, so
that we can reuse this function in other tests, e.g. the test for
live-migration with numa.

Despite setting up a dedicated thread for signal handling, we weren't
making sure that the signals we were listening for there were actually
dispatched to the right thread. While the signal-hook provides an
iterator API, so we can know that we're only processing the signals
coming out of the iterator on our signal handling thread, the actual
signal handling code from signal-hook, which pushes the signals onto
the iterator, can run on any thread. This can lead to seccomp
violations when the signal-hook signal handler does something that
isn't allowed on that thread by our seccomp policy.
To reproduce, resize a terminal running cloud-hypervisor continuously
for a few minutes. Eventually, the kernel will deliver a SIGWINCH to
a thread with a restrictive seccomp policy, and a seccomp violation
will trigger.
As part of this change, it's also necessary to allow rt_sigreturn(2)
on the signal handling thread, so signal handlers are actually allowed
to run on it. The fact that this didn't seem to be needed before
makes me think that signal handlers were almost _never_ actually
running on the signal handling thread.

Move the processing of the input from stdin, PTY or file from the VMM
thread to the existing virtio-console thread. The handling of the resize
of a virtio-console has not changed but the name of the struct used to
support that has been renamed to reflect its usage.

Downcasting of GicDevice trait might fail. Therefore we try to
downcast the trait first and only if the downcasting succeeded we
can then use the object to call methods. Otherwise, do nothing and
log the failure.

This commit implements the GIC (including both GICv3 and GICv3ITS)
Pausable trait. The pause of device manager will trigger a "pause"
of GIC, where we flush GIC pending tables and ITS tables to the
guest RAM.

This test exercises the local live-migration between two Cloud
Hypervisor VMs on the same host. It ensures the following behaviors:
1. The source VM is up and functional (including various virtio-devices
are working properly);
2. The 'send-migration' and 'receive-migration' command finished
successfully;
3. The source VM terminated gracefully after live migration;
4. The destination VM is functional (including various virtio-devices
are working properly) after live migration.
Note: This test does not use vsock as we can't create two identical
vsock on the same host.

This patch adds a dedicate function to include the common checks on the
virtio-devices from the 'test_snapshot_restore' test, which will also be
reused for the upcoming 'test_live_migration' test.

This prevents the boot of the guest kernel from being blocked by
blocking I/O on the serial output since the data will be buffered into
the SerialBuffer.
Fixes: #3004
Signed-off-by: Rob Bradford <robert.bradford@intel.com>
Introduce a dynamic buffer for storing output from the serial port. The
SerialBuffer implements std::io::Write and can be used in place of the
direct output for the serial device.
The internals of the buffer is a vector that grows dynamically based on
demand up to a fixed size at which point old data will be overwritten.
Currently the buffer is only flushed upon writes.

The rust-vmm crates we're pulling from git have renamed their main

Moving to the latest kernel 5.14 simplifies greatly the list of patches
