Merge remote-tracking branch 'afaerber/tags/qom-cpu-for-anthony' into staging

QOM CPUState refactorings

* Fix for OpenRISCCPU subclasses
* Fix for gdbstub CPU selection
* Move linux-user CPU functions into new header
* CPUState part 10 refactoring: first_cpu, next_cpu, cpu_single_env et al.
* Fix some targets to consistently inline TCG code generation
* Centrally log CPU reset
