    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.
