40daca54cd aio / timers: Rearrange timer.h & make legacy functions call non-legacy
Rearrange timer.h so it is in order by function type.

Make legacy functions call non-legacy functions rather than vice-versa.

Convert cpus.c to use new API.

ac70aafc28 aio / timers: Use all timerlists in icount warp calculations
Notify all timerlists derived from vm_clock in icount warp
calculations.

When calculating timer delay based on vm_clock deadline, use
all timerlists.

For compatibility, maintain an apparent bug where when using
icount, if no vm_clock timer was set, qemu_clock_deadline
would return INT32_MAX and always set an icount clock expiry
about 2 seconds ahead.

NB: thread safety - when different timerlists sit on different
threads, this will need some locking.

594a45ce64 cpus: Let vm_stop[_force_state]() always flush block devices
Even if the VM is already stopped, we cannot assume that all data has
already been successfully flushed to disk. The flush during the previous
vm_stop() could have failed.

Run bdrv_flush_all() unconditionally so that we get an error each time
if the block device isn't really flushed.

215e79c01c KVM: Don't assume that mpstate exists with in-kernel PIC always
On PPC, we don't support MP state. So far it's not necessary and I'm
not convinced yet that we really need to support it ever.

However, the current idle logic in QEMU assumes that an in-kernel PIC
also means we support MP state. This assumption is not true anymore.

Let's split up the two cases into two different variables. That way
PPC can expose an in-kernel PIC, while not implementing MP state.
