cons2 non-us keymap

Hi,

in-head translation of keyboards are a nightmare.
I modified the cons2 server slightly to support non-us keyboards.

I don't think the monolith way of file stored mappings is needed for
c/s systems. It isn't hard to recompile a small server.

For that reason I only modified the makefile to support a LANG
variable, changed the state machine in isr.c to recognize the extra
shift key (alt graphics), and moved the language dependend mapping
tables out of isr.c into LANG-dependend files (mapus.c and mapde.c
kinda file stored mappings). I'm not sure whether this approach
disturbs US people or not because I don't know about the behavior of
the right alt key on these keyboards. Maybe we need a generalized
isr.c.

I don't have experiences in creating diff files suitable for patch.
But I don't feel like learning it yet. The following patch did it's
job on the makefile and isr.c for me but not for map??.c so I'll
append them.

Have fun.

---------- patch for makefile and isr.c------------
