This is a copy of udev/src/keymap from https://bitbucket.org/braindamaged/udev/overview
but modified to compile standalone. It comes from circa Dec 2012, that's the last
commit date.

The new udev (from July onwards) remove the keymap utility, see:
http://lists.freedesktop.org/archives/systemd-devel/2013-July/011773.html
This is another brain-damaged move from the systemd team 
because not all devices can run with DMI enabled; so it needs
another mechanism of setting up keymaps, of which this is ideal. 

The only thing I change the Makefile; the rest is identical.
Note that there is no "configure" and no "make install" - you need to know
where to copy the files.
