[PATCH 0/6] coroutine: new sleep/wake API

[Paolo Bonzini <pbonzini@redhat.com>]

This is a revamp of the qemu_co_sleep* API that makes it easier to
extend the API: the state that is needed to wake up a coroutine is now
part of the public API instead of hidden behind a pointer-to-pointer;
the API is made more extensible by pushing the rest of QemuCoSleepState
into local variables.

In the future, this will be extended to introduce a prepare/sleep/cancel
API similar to Linux's prepare_to_wait/schedule/finish_wait functions.
For now, this is just a nice refactoring.

Paolo Bonzini (6):
  coroutine-sleep: use a stack-allocated timer
  coroutine-sleep: disallow NULL QemuCoSleepState** argument
  coroutine-sleep: allow qemu_co_sleep_wake(NULL)
  coroutine-sleep: move timer out of QemuCoSleepState
  coroutine-sleep: replace QemuCoSleepState pointer with struct in the
    API
  coroutine-sleep: introduce qemu_co_sleep
