    libxl: Add lock process indicator to saved VM state
    
    Commit fa58f571ee added a lock processes indicator to the
    libxlDomainObjPrivate struct to note that a lock process was
    successfully started for the VM. However, the commit neglected to
    add the indicator to the VM's saved state file. As a result, the
    indicator is lost on libvirtd restart, along with the knowledge of
    whether a lock process was started for the VM.
    
    This change adds support for the indicator in the domainObjPrivate
    data parse and format callbacks, ensuring its value survives libvirtd
    restarts.
