replacing umlaute and fixing address in headers Haldeneggsteig -> Universitaetsstrasse

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

Added: initial version of new xeon phi loader

newlib,x86_32: use PRI{u,x}32, PRI{u,x}PTR, etc in format strings

Again this is needed because newlib defines uint32_t as unsigned long.
(In retrospect, I should just changed newlib's uint32_t to unsigned int)

Checkpoint:
compiles and boots qemu for x86-{32,64}-{newlib,freec}
Also, a couple of tests on real hardware (x86_64 only) work

Initial version of public stable barrelfish repository.
