This is a preparation step for some refactoring of the XML parser, see https://listman.redhat.com/archives/libvir-list/2021-March/msg01066.html Many libvirt structs have members that are of type `int` but actually are virTristateBool or virTristateSwitch. Fix this to increase type safety. Note that the comments on `virStorageAdapterFCHost::managed` and `virStoragePoolSourceDevice::part_separator` (patches #12 and #13) were actually wrong.
