usb-host: rip out legacy procfs support
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.

target-i386: fix dpps and dppd SSE2 instructions
The helpers implemented dpps and dppd SSE instructions are not passing
the correct argument types to the softfloat functions. While they do
work anyway providing a correct behaviour, this patch fixes that.
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.

printed a lot of output)
* a number of CPUs only supported as guests were included in the

in a late compile failure on those systems rather than a
configure failure or fallback to TCI
* bailing out for an unsupported CPU happened before the main
