Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into staging

- Many fixes from the floor as usual
- New "edu" device (v1->v2: fix 32-bit compilation)
- Disabling HLE and RTM on Haswell & Broadwell
- kvm_stat updates
- Added --enable-modules to Travis, in preparation for switching
  the default
