[libvirt] [PATCHv2 00/14] Fix vmdef usage after ExitMonitor

[Ján Tomko]

Patches 3-8 fix possible crash/invalid memory access if QEMU crashes
while we're in the monitor.
Patches 9-13 change all other callers of qemuDomainObjExitMonitor
to exit early in that case, but should not fix any real issues.
They are necessary to turn on ATTRIBUTE_RETURN_CHECK for the ExitMonitor
call.

  Fix vmdef usage while in monitor in qemuDomainHotplugVcpus
  Fix vmdef usage while in monitor in BlockStat* APIs
  Fix vmdef usage while in monitor in qemu process
  Exit early after domain crash in monitor on device hotplug
  Exit early after domain crash in monitor on migration
  Exit early after domain crash in monitor in qemu_process
  Exit early after domain crash in monitor in qemu_driver
  Exit early after domain crash in monitor on snapshots
  Add ATTRIBUTE_RETURN_CHECK to qemuDomainObjExitMonitor
