Add a DTrace tracing backend targetted for SystemTAP compatability
This introduces a new tracing backend that targets the SystemTAP
implementation of DTrace userspace tracing. The core functionality
should be applicable and standard across any DTrace implementation
on Solaris, OS-X, *BSD, but the Makefile rules will likely need
some small additional changes to cope with OS specific build
requirements.
This backend builds a little differently from the other tracing
backends. Specifically there is no 'trace.c' file, because the
'dtrace' command line tool generates a '.o' file directly from
the dtrace probe definition file. The probe definition is usually
named with a '.d' extension but QEMU uses '.d' files for its
external makefile dependancy tracking, so this uses '.dtrace' as
the extension for the probe definition file.
The 'tracetool' program gains the ability to generate a trace.h
file for DTrace, and also to generate the trace.d file containing
the dtrace probe definition.
Example usage of a dtrace probe in systemtap looks like:
probe process("qemu").mark("qemu_malloc") {
printf("Malloc %d %p\n", $arg1, $arg2);

PCI: Bus number from the bridge, not the device
pcibus_dev_print() was erroneously retrieving the device bus
number from the secondary bus number offset of the device
instead of the bridge above the device. This ends of landing
in the 2nd byte of the 3rd BAR for devices, which thankfully
is usually zero.
Note: pcibus_get_dev_path() copied this code,
inheriting the same bug. pcibus_get_dev_path() is used for
ramblock naming, so changing it can effect migration. However,
I've only seen this byte be non-zero for an assigned device,
which can't migrate anyway, so hopefully we won't run into
any issues.
This patch does not touch pcibus_get_dev_path, as
bus number is guest assigned for nested buses,

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,
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.
