To answer the question from the cover letter: For internal types, we put the G_DEFINE_AUTO in the header files introducing the particular type. For types from external libraries (like libxml2), we put them into the header file with our wrappers over it. For public libvirt types, IIRC we only have defined the cleanup functions privately in virsh (tools/virsh-util.h) And this one does not need the define, we simply use g_autofree for types that are freed by g_free.
