121729a3b0 vmm: Split signal handling for VM and VMM signals
The VM specific signal (currently only SIGWINCH) should only be handled
when the VM is running.

The generic VMM signals (SIGINT and SIGTERM) need handling at all times.

Split the signal handling into two separate threads which have differing
lifetimes.

Tested by:
1.) Boot full VM and check resize handling (SIGWINCH) works & sending
    SIGTERM leads to cleanup (tested that API socket is removed.)
2.) Start without a VM and send SIGTERM/SIGINT and observe cleanup (API
    socket removed)
3.) Boot full VM, delete VM and observe 2.) holds.
4.) Boot full VM, delete VM, recreate VM and observe 1.) holds.

Fixes: #4269

e300c3dcf7 vhdx: Avoid unwrap() of invalid header
In the original code:

If the first header was invalid and the second header had the same
sequence number (zero) then the invalid first header would be returned.

The new code is more Rust idiomatic and avoids this situation.

f94a5fb4e3 virtio-devices: Pass negotiated queue size to vhost-user backend
The vhost-user backend was always provided the maximum queue size but
this is incorrect. Instead it must be informed of the actual queue size
that has been negotiated with the virtio driver running in the guest.

This ensures proper functioning of vhost-user-block with the Rust
Hypervisor Firmware, which uses a hardcoded queue size of 16.

Partially fixes #4285

00800b8499 virtio-devices: Remove deprecated call to VHOST_USER_RESET_OWNER
The latest vhost-user specification describes VHOST_USER_RESET_OWNER
command as deprecated with the following explanation:

  This is no longer used. Used to be sent to request disabling all
  rings, but some back-ends interpreted it to also discard connection
  state (this interpretation would lead to bugs). It is recommended that
  back-ends either ignore this message, or use it to disable all rings.

Also, it's been observed that when using either Rust Hypervisor Firmware
or EDK2 OVMF firmware with SPDK (using the block device as the boot
disk), the virtio reset that happens when the firmware no longer needs
to access the block device caused a failure by triggering the command
VHOST_USER_RESET_OWNER.

For all these reasons, this patch simplifies the virtio reset
implementation by simply disabling the virtqueues and no longer calling
into VHOST_USER_RESET_OWNER.

Partially fixes #4285

93237f0106 vmm: Set MADT "Online Capable" flag
The Linux kernel now checks for this before marking CPUs as
hotpluggable:

commit aa06e20f1be628186f0c2dcec09ea0009eb69778
Author: Mario Limonciello <mario.limonciello@amd.com>
Date:   Wed Sep 8 16:41:46 2021 -0500

    x86/ACPI: Don't add CPUs that are not online capable

    A number of systems are showing "hotplug capable" CPUs when they
    are not really hotpluggable.  This is because the MADT has extra
    CPU entries to support different CPUs that may be inserted into
    the socket with different numbers of cores.

    Starting with ACPI 6.3 the spec has an Online Capable bit in the
    MADT used to determine whether or not a CPU is hotplug capable
    when the enabled bit is not set.

adf5881757 build: #[allow(clippy::significant_drop_in_scrutinee) in some crates
This check is new in the beta version of clippy and exists to avoid
potential deadlocks by highlighting when the test in an if or for loop
is something that holds a lock. In many cases we would need to make
significant refactorings to be able to pass this check so disable in the
affected crates.
