[libvirt] [libvirt-designer PATCHv2] Add GvirDesignerDomain::osinfo_db

virtxml was doing its own loading of the libosinfo database,
and gvir_designer_init() was loading it a second time.
By adding a GVirDesignerDomain::osinfo_db property, applications
can share the same OsinfoDb as libvirt-designer. The association
is made per libvirt-designer domain for more flexibility.
If no OsinfoDb is associated with a domain when needed,
libvirt-designer will automatically try to load it.
