[PATCH qemu-server v4 0/3] add pvpanic device support

[Kaiyang Wu <wukaiyang2003@gmail.com>]

This patchset adds pvpanic device support to QEMU virtual machines to
provide extra virtual machine status (guest-panicked) when virtual
machines panic [0] and perform panic actions.

v1: https://lore.proxmox.com/pve-devel/20260827103529.393388-1-wukaiyang@loongfans.cn/
v2: https://lore.proxmox.com/pve-devel/20260914092015.125780-1-wukaiyang@loongfans.cn/
v3: https://lore.proxmox.com/pve-devel/20261009065813.109006-1-wukaiyang@loongfans.cn/

Changes v1 -> v2:
- Remove the pvpanic ISA device support to simplify the code
- Move the pvpanic setting from Hardware to Options
- Restart a HA-managed VM when it panics to restore the "started" state

Changes v2 -> v3:
- Allow to set panic action. The HA stack automatically restarts a panicked VM
  when the VM exits using the 'exit-failure' panic action

Changes v3 -> v4:
- Specify the default panic action (shutdown) in the 'pvpanic_fmt' schema
- Mention only the default panic action in the documentation
- Mention only since when the pvpanic-pci device is supported in the Linux kernel in the documentation
- Briefly mention Windows VirtIO Drivers in the pvpanic section
- Make panic actions translatable in the manager
