This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
