Here is again the full series for Win32 iothread support. It should be
ready now.
Patches 1 to 5 are generic Win32 improvements, including the qemu-thread
implementation. To simplify the dependencies, I think it's better if
this part is also routed through uq/master.

We have qemu_cpu_self and qemu_thread_self. The latter is retrieving the

Right now, rt_clock timers are limited to millisecond resolutions;
other clocks are limited to nanoseconds. This patch series removes
the limitation.
In order to ease transition, new functions are provided with
explicit resolution (milli/nanosecond). The old qemu_get_clock

These patches are already not doing a great service to out-of-tree
modifications to QEMU. However, at least we can warn them by getting
rid of the old confusing functions, or otherwise causing compilation
errors. This patch removes qemu_get_clock; the previous one changed

This was done with:
sed -i '/get_clock\>.*rt_clock/s/get_clock\>/get_clock_ms/' \

The following conditions can cause cpu_has_work(env) to become true:
- env->queued_work_first: run_on_cpu is already kicking the VCPU
- env->stop = 1: pause_all_vcpus is already kicking the VCPU
- env->stopped = 0: resume_all_vcpus is already kicking the VCPU
- vm_running = 1: vm_start is calli
This enables rt_clock timers to use nanosecond resolution, just by
using the _ns functions; there is really no reason to forbid that.
Migrated timers are all using vm_clock (of course; but I checked that
anyway) so the timers in the savevm files are already in nanosecond
resolution. So this patch
Whenever env->created becomes true, qemu_cpu_cond is signaled by
