- Add support for libusbhid in 32-bit compatibility mode.
- Add missing check for ugd_actlen being too small.
- Add missing inclusion guard to usbvar.h header file.
- This also fixes buildworld breakage since r213852.

Merge improvements from kernel HID parser to the userland usbhid(3)
parser. This merge does not change any API and should not break any
native or thirdparty applications.

Changes include:

* Merge multiple report ID support and other improvements from kernel
HID parser.
* Ignore rid argument in hid_start_parser, parse all the report items since
we now support multiple report ID.
* Skip report ID byte in hid_get_data() and set report ID byte in
hid_set_data(), if report ID is non-zero.
* Reimplement hid_get_report_id: instead get report id from uhid device
(which is always 0), try parsing the report descriptor and return the
first report ID encountered.

Patches to make libusbhid and HID userland utilities compatible with
the new USB stack. All HID ioctls should go through the libusbhid
library to ensure compatibility. I have found at least one piece of
software in /usr/ports which needs to get updated before USB HID
devices will work. This is the X joystick input driver.
