[PATCH qemu-server 0/1] fix #7590: qemu-server: apply timeout to QEMU start fork

[Samuel Rufinatscha <s.rufinatscha@proxmox.com>]

This series makes the forked QEMU start path use the existing start
timeout.

If the timeout expires, it terminates processes in the VM scope and
cleans up QSD before reporting the start failure. This prevents a stuck
qmstart task from holding the VM config lock indefinitely or leaving a
partially started QEMU process running.

Tested with QEMU blocked on a FIFO (see the reproducer at [0]).
qmstart timed out and released the lock, leaving no active scope or
QEMU process. Normal VM startup still works.
