To allow modifications to the lists to be synchronized, convert virPCIDeviceList and virUSBDeviceList into virObjectLockable classes. The locking, however, will not be self-contained. The users of these classes will have to call virObjectLock/Unlock in the critical regions. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
