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

Windows 7 may use the same stream number for input and output.
That will result in lot of garbage on playback.
The hardcoded value of 4 needs to be in sync with GCAP streams
description and IN/OUT registers.

msi_init may fail, so we need to check on uninit if the cap was
actually installed. This also avoids that the users need to check.

This was done with:
sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \
$(git grep -l 'qemu_get_clock\>' )
sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
$(git grep -l 'qemu_new_timer\>' )
after checking that get_clock and new_timer never occur twice
on the same line. There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.
There was exactly one false positive in qemu_run_timers:
- current_time = qemu_get_clock (clock);
+ current_time = qemu_get_clock_ns (clock);
which is of course not in this patch.

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.
This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

The HDA bus supports up to 15 codecs, with addresses 0 ... 14.
We get that wrong in two places:
* When handing out addresses we accept address 15 as valid.
* The bitmasks for two registers (WAKEEN and STATESTS) don't
have bit 14 set.
This patch fixes it.

This patch adds MSI support to the intel hda audio driver. It is
enabled by default, use '-device intel-hda,msi=0' to disable it.

Also add an exit callback to the HDA bus implementation and make sure
it is called on qdev_free().

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.
