Keysym collisions make it impossible to create certain keymaps

[Julian Yon]

Some combinations of keysyms can't be used together in the same keymap because they share the same lower 16 bits, which is used as the index for the table. Attached is a patch which fixes that. Written against rdesktop 1.7.1 as this is the version in Ubuntu, but appears to apply cleanly to trunk. I've sent this patch upstream but am reporting it here as well because movement there seems slow.

Ubuntu version: Ubuntu Studio 13.04
uname -a: Linux numenor 3.8.0-29-lowlatency #21-Ubuntu SMP PREEMPT Thu Aug 15 12:50:08 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
rdesktop version: 1.7.1-1ubuntu1
What I expected to happen: Custom keymap works correctly
What actually happened: Some keys produced the wrong character because they shared the same least significant 16 bits

As an example of a keymap that doesn't work without this patch, see my Colemak keymap at:
