rfc: import usbhidctl(1) from OpenBSD

[Rene Ladan]

Hi,

I was thinking about the idea of sending a PR to replace our
usbhidctl(1) with that of OpenBSD/NetBSD.

It has the following advantages:
* the -w option hopefully works, the implementation of PR usb/103418
seems to be buggy
* the command 'usbhidctl -f DEV item' to display the value of a single
item actually works (our implementation returns nothing)
* in sync with OpenBSD and NetBSD
* my own PR usb/103418 and docs/103420 can be trashed.

I've sucessfully tested OpenBSD's usbhidctl(1)
(http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/usbhidctl/usbhid.c,
revision 1.7) with an Xbox 360 controller (the output report descriptor
is under development).
It compiles fine after applying the attached patch using `cc usbhid.c -o
OUTFILE -lusbhid`.

Regards,
Rene
