Our hda codecs exist in two variants: With CONFIG_MIXEMU=y they expose
amplifiers for volume control to the guest, with CONFIG_MIXEMU=n they
don't.
This patch changes the codec ids, they are different now for these two
cases. This makes sure windows guests will notice the difference.

It's identical to the hda-duplex codec, except that it advertises the
input as microphone instead of line-in and the output as speaker instead
of line-out. Some guest apps (microsoft netmeeting being one) are picky
when it comes to selecting the recording source and don't accept
line-in, so give them what they expect.

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.

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.

We already have a QOM interface for this so let's use it.

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.

Windows 7 may use the same stream number for input and output.
Current code will confuse streams.
Changes since v1:
- keep running_compat[] for migration version 1
- add running_real[] for migration version 2

on exit.

This patch adds three devices to qemu:
intel-hda
Intel HD Audio Controller, the PCI device. Provides a HDA bus.
Emulates ICH6 at the moment. Adding a ICH9 PCIE
variant shouldn't be hard.
hda-duplex
HDA Codec. Attaches to the HDA bus. Supports 16bit stereo,
rates 16k -> 96k, playback, recording and volume control
(with CONFIG_MIXEMU=y).
hda-output
HDA Codec without recording support. Subset of the hda-duplex
codec. Use this if you don't want your guests access your mic.
Usage: add '-device intel-hda -device hda-duplex' to your command line.
Tested guests:
* Linux works.
* Win7 works.
* DOS (mpxplay) works.
* WinXP doesn't work.
[ v2 changes ]
* Fixed endianess, big endian hosts work now.
* Fixed some emulation bugs.
* Added immediate command emulation.
* Added vmstate support.
* Make it behave like all other sound card drivers:
- can be configured via '--audio-card-list=hda'
- can be added to a VM using '-soundhw hda'
* Code style fixups.
* Zapped guest-triggerable asserts.
* Handle partial reads/writes of audio data correctly.
