replacing umlaute and fixing address in headers Haldeneggsteig -> Universitaetsstrasse

Signed-off-by: Reto Achermann <reto.achermann@inf.ethz.ch>

Mackerel now allows "noaddr" registers, which can model co-processors, etc.
This allows considerable cleanup in the x86 code; 32-bit on the way soon.
Redundant ia32_spaces header, since this was not used.
Documented extensions to Mackerel syntax.

Fixed weird crashing bug.
