- Update to Xen 4.1.2_rc3 c/s 23171

- bnc#720054 - Changed /etc/udev/rules.d/40-xen.rules to not run
  Xen's vif-bridge script when not running Xen.  This is not a
  solution to the bug but an improvement in the rules regardless.
  Updated udev-rules.patch

- Add pciback init script and sysconf file, giving users a simple
  mechanism to configure pciback.
  init.pciback sysconfig.pciback

- update scripts to use xl -f, or xm if xend is running:
  xen-updown.sh, init.xendomains, xmclone.sh

x86/vmx: Small fixes to MSR_IA32_VMX_PROCBASED_CTLS feature probing.
Should check for VIRTUAL_INTR_PENDING as we unconditionally make use
of it. Also check for CR8 exiting unconditionally on x86/64, as this
is of use to nestedvmx, and every 64-bit cpu should support it.
