[libvirt PATCH v2 11/31] qemu_blockjob: process QEMU_MONITOR_JOB_STATUS_PENDING signal
QEMU emits this signal when the job finished its work and is about to be
finalized. If the job is started with autofinalize disabled the job
waits for user input to finalize the job.
This will be used by snapshot delete code.
