7a608f562e hw: Fix return value check for bdrv_read, bdrv_write
Those functions return -errno in case of an error.
The old code would typically only detect EPERM (1) errors.

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.

999e12bbe8 sysbus: apic: ioapic: convert to QEMU Object Model
This converts three devices because apic and ioapic are subclasses of sysbus.
Converting subclasses independently of their base class is prohibitively hard.

751c6a1704 kill drives_table
First step cleaning up the drives handling.  This one does nothing but
removing drives_table[], still it became seriously big.

drive_get_index() is gone and is replaced by drives_get() which hands
out DriveInfo pointers instead of a table index.  This needs adaption in
*tons* of places all over.

The drives are now maintained as linked list.
