2022-10-28accel/qtest: Support qtest accelerator for WindowsXuzhou Cheng
Currently signal SIGIPI [=SIGUSR1] is used to kick the dummy CPU when qtest accelerator is used. However SIGUSR1 is unsupported on Windows. To support Windows, we add a QemuSemaphore CPUState::sem to kick the dummy CPU instead for Windows.

2021-02-05accel: replace struct CpusAccel with AccelOpsClassClaudio Fontana
This will allow us to centralize the registration of the cpus.c module accelerator operations (in accel/accel-softmmu.c), and trigger it automatically using object hierarchy lookup from the new accel_init_interfaces() initialization step, depending just on which accelerators are available in the code. Rename all tcg-cpus.c, kvm-cpus.c, etc to tcg-accel-ops.c, kvm-accel-ops.c, etc, matching the object type names.
