hda: add hda-micro codec

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...

hda: fix codec ids

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....

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...

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

qdev: move qdev->info to class

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.

hda: do not mix output and input stream states, RHBZ #740493

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...

Add Intel HD Audio support to qemu.

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,...
