This converts two types because smbus is implemented as a subclass of i2c. It's

This converts two devices at once because PIC subclasses ISA and converting

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.

Since we are still dynamically creating TypeInfo, we need to chain the
class_init function in order to be able to make use of it within subclasses of
TYPE_DEVICE.
This will disappear once we register TypeInfos directly.

In order to introduce inheritance while still using the qdev registration
interfaces, we need to be able to use a parent other than TYPE_DEVICE. Add a
new interface that allows this.

Right now, DeviceInfo acts as the class for qdev. In order to switch to a
proper ObjectClass derivative, we need to ween all of the callers off of
interacting directly with the info pointer.

This is a very shallow integration. We register a TYPE_DEVICE but only use
QOM as basically a memory allocator. This will make all devices show up as
QOM objects but they will all carry the TYPE_DEVICE.

Limit the return value (corresponding to the length of the buffer to be
DMAed back to the intiator) to the value in req->cmd.xfer, which is the
amount of data that the initiator expects. Eliminate now-duplicate code
that does this guarding in the functions for individual commands.
Without this, the SCRIPTS code in the emulated LSI device eventually
raises a DMA interrupt for a data overrun when an INQUIRY command whose
buflen exceeds req->cmd.xfer is processed. It's the responsibility of
the client to provide a request buffer and allocation length that are
large enough for the result of the command.

The new block was filled with zero when it was allocated by g_malloc0,
but when it was reused later and only partially used, data from the
previously allocated block were still present and written to the new
block.
This caused the problems reported by bug #919242
(https://bugs.launchpad.net/qemu/+bug/919242).
Now the unused parts of the new block which are before and after the data
are always filled with zero, so it is no longer necessary to zero the whole
block with g_malloc0.
I also updated the copyright comment.

Unplugging a storage interface like virtio-blk causes the host block
device to be deleted too. Long-running operations like block migration
must take a DriveInfo reference to prevent the BlockDriverState from
being freed. For image streaming we can do the same thing.
Note that it is not possible to acquire/release the drive reference in
block.c where the block job functions live because
drive_get_ref()/drive_put_ref() are blockdev.c functions. Calling them
from block.c would be a layering violation - tools like qemu-img don't
even link against blockdev.c.
