[5589] target-ppc: xer access prototypes no more used & implemented

Revision: 5589

target-ppc: xer access prototypes no more used & implemented

Revision 5500 of the qemu repository removed all code using
ppc_load_xer & ppc_store_xer as well as their implementation.

Another patch fixes it's usage in kvm-userspace for powerpc, but I think
that header can now be cleaned up, therefore this patch to qemu-devel.

CVE-2008-4539: fix a heap overflow in Cirrus emulation

The code in hw/cirrus_vga.c has changed a lot between CVE-2007-1320 has
been announced and the patch has been applied. As a consequence it has
wrongly applied and QEMU is still vulnerable to this bug if using VNC.

The default max number of CPU has been set to 1 in revision 5566, so
this patch is not necessary anymore.
