[RFC PATCH 00/19] accel: Introduce AccelvCPUState opaque structure

[Philippe Mathieu-Daudé]

Hi,

This series introduces the 'AccelvCPUState' which is forward
declared opaque in "cpu.h", then each accelerator define it.

The opaque CPUState::accel_vcpu pointer is shared by all
accelerators (not a problem because there can be at most
one accelerator per vCPU).

Series is organized as:
- preliminary trivial cleanups
- introduce AccelvCPUState
- move WHPX fields (build-tested)
- move HAX fields (not tested)
- move KVM fields (build-tested)
- move HVF fields (not tested)

For now vcpu_dirty is still shared in CPUState.

Sending as RFC to see if it is worthwhile.

Regards,

Phil.
