This brings a usb audio device to qemu. Output only, fixed at
16bit stereo @ 480000 Hz. Based on a patch from
H. Peter Anvin <hpa@linux.intel.com>
Usage: add '-device usb-audio' to your qemu command line.
Works sorta ok on a idle machine. Known issues:
* Is *very* sensitive to latencies.
* Burns quite some CPU due to usb polling.
In short: It brings the qemu usb emulation to its limits. Enjoy!

This patch removes support for parsing /proc/bus/usb/devices for device
discovery. The code lacks a few features compared to the sysfs code and
is also bitrotting as everybody has sysfs these days.
This implies having sysfs mounted is mandatory now to use the usb-host
driver. udev isn't required though. qemu will prefer the udev-managed
device nodes below /dev/bus/usb, but in case this directory isn't preset
qemu will use the device nodes below /proc/bus/usb (default usbfs mount
point).
Bottom line: make sure you have both sysfs and usbfs mounted properly,
and everything should continue to work as it did before.

The fixes to qapi code generation had multiple bugs:
- the Null class used to drop output was missing some methods
- in some scripts it was never instantiated, leading to a None return,
which is missing even more methods
- the --source and --header options were swapped
Luckily, all those bugs were hidden by a makefile bug which caused the
old behaviour (with the race) to be invoked.

SSE rounding and flush to zero control has never been implemented. However
given that softfloat-native was using a single state for FPU and SSE and
given that glibc is setting both FPU and SSE state in fesetround(), this
was working correctly up to the switch to softfloat.
Fix that by adding an update_sse_status() function similar to
update_fpu_status(), and callin git on write to mxcsr.

roundps and roundss SSE2 instructions have been broken when switching
target-i386 to softfloat. They use float64_round_to_int to convert a
float32, and while the implicit conversion from float32 to float64 was
correct for softfloat-native, it is not for pure softfloat. Fix that by
using the correct registers and correct functions.
Also fix roundpd and roundsd implementation at the same time, even if
these functions are behaving correctly.

minpd, minps, minsd, minss and maxpd, maxps, maxsd, maxss SSE2
instructions have been broken when switching target-i386 to softfloat.
It's not possible to use comparison instructions on float types anymore
to softfloat, so use the floatXX_lt function instead, as the
float_XX_min and float_XX_max functions can't be used due to the Intel
specific behaviour.
As it implements the correct NaNs behaviour, let's remove the
corresponding entry from the TODO.
It fixes GDM screen display on Debian Lenny.

Coverity complained about local variable key which was only partially
initiated. Only key.st_value was set. As this was also the only part
of key which was used in function symfind, the code could be optimized
by directly passing a pointer to orig_addr.
In bsd-user/elfload.c, fix ec822001a2
was missing. This was a simple replacement of > by >= in symfind, so
I fixed it here without creating an additional patch.
