83f7d43a9e 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.

39bffca203 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
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.

e855761ca8 qdev: prepare source tree for code conversion
These are various small stylistic changes which help make things more
consistent such that the automated conversion script can be simpler.

It's not necessary to agree or disagree with these style changes because all
of this code is going to be rewritten by the patch monkey script anyway.

61d9d6b091 ide: Register vm change state handler once only
We register the vm change state handler in a PCI BAR map() function.
This function can be called multiple times throughout the lifetime of a
PCI IDE device.  This results in duplicate vm change state handlers
being register, none of which are ever unregistered.

Instead, register the vm change state handler in the device's init
function once and for all.

b80d4a9887 pci: don't overwrite multi functio bit in pci header type.
Don't overwrite pci header type.
Otherwise, multi function bit which pci_init_header_type() sets
appropriately is lost.
Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero
which is already zero cleared.

how to test:
run qemu and issue info pci to see whether a device in question is
normal device, not pci-to-pci bridge.
This is handy because guest os isn't required.

Instead of doing tricks to get the pci_dev, just pass it in the 1st
place.  Patch is a bit longer that reverting the pci_dev field, but it
states more clearly (IMHO) what we are doing.

It also fixes the bm test, now that you told me that ->unit is not
always valid.

90228ee395 workaround for cmd646 bmdma register access while no dma is active
This is a workaround only, and is a partial revert
of a few changes to BMDMAState which removed pci_dev
field on the way.

- cmd646 pci_from_bm() expects bm->unit value to
correspond with bm data being passed to callback
as opaque pointer. This breaks when write to dma
control register of second channel happens when no
dma operation is in progress, so bm->unit is zero
for second channel, and pci_from_bm() returns garbage
pointer. Crash happens shortly after that while
dereferencing that pointer.

v0->v1: cleaned up dead code from pci_from_bm.
