qom: Unify type registration

Replace device_init() with generalized type_init().

While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace....

qdev: register all types natively through QEMU Object Model

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...

ac97: don't override the pci subsystem id

This patch removes the code lines which set the subsystem id for the
emulated ac97 card to 8086:0000. Due to the device id being zero the
subsystem id isn't vaild anyway. With the patch applied the sound card
gets the default qemu subsystem id (1af4:1100) instead....

qdev: add return value to init() callbacks.

Sorry folks, but it has to be. One more of these invasive qdev patches.

We have a serious design bug in the qdev interface: device init
callbacks can't signal failure because the init() callback has no
return value. This patch fixes it....
