auto-generated USB keyboard maps

[Miod Vallat <miod_(_at_)_online_(_dot_)_fr>]

I couldn't help but notice that the USB keyboard maps are very similar
to the PS/2 keyboard maps, with different the scan codes. So I enhanced
the hppa gsc keyboard map munger to do the PS/2 -> USB conversion.

Pros:
- brings us more USB keyboard layouts (RU, UA, LT, LA, BR, TR, PL, HU,
  SI)
- you can enter ddb using the right control key (previously, it would
  only work with the left one)
- easier maintainance!

If you want to test this (and I would appreciate test reports for non-US
layouts), apply the diff in sys/dev/usb, then don't forget to run "make"
in the same directory after applying, or you will still be using the old
code. Then recompile a kernel as ususal.

On some layouts, KC(49) becomes KC(50). I consider these as bugfixes to
the existing layouts, which lacked consistency between these scancodes.
Let me know if I am wromg here.

US and FR layouts have been tested to work correctly.
