Add a vhost-user sound device to cloud-hypervisor, enabling audio passthrough via an external vhost-user sound backend daemon. The implementation mirrors the existing vhost-user GPU device. The sound device uses 4 virtqueues (control, event, tx, rx) per the virtio sound specification, and sets SCHED_FIFO priority 88 on its epoll thread for low-latency audio processing. Changes span the full stack: - vm-virtio: Sound = 25 device type registration - virtio-devices: Sound device implementation, seccomp filters, ActivateError variant - vmm: SoundConfig, CLI --sound argument, OpenAPI spec, device manager wiring, seccomp filters updated for sched_setscheduler Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
