Merge remote-tracking branch 'remotes/ehabkost/tags/x86-pull-request' into staging

X86 queue, 2015-07-15

Two bug fixes:
* Memory leak due to extra g_strdup() when registering X86CPU alias properties
* Fix CPUID levels so that W10 insider can run as guest OS

* remotes/ehabkost/tags/x86-pull-request:
  target-i386: emulate CPUID level of real hardware
  target-i386: Don't strdup() alias property name
