usbview 2.1 release

[Greg KH <greg@kroah.com>]

After 9 years, I figure it's about time for a new release of usbview, as
some people still use it, and there's been some grumbling about a
release by the distro packages that have to deal with it.

Nothing big in here, just loads of build configuration changes in order
to keep the thing building properly within most modern Linux systems,
and a few other small changes.  Full changelog is at the bottom of this
email.

Ideally in the future, this will move into the usbutils package, when I
get some free time, and remove it from the need to access the debugfs
file and take advantage of the extended device structure parsing that
'lsusb' provides.

The package can be downladed at:
