qemu_co_queue_next does not need to release and re-acquire the mutex, because the queued coroutine does not run immediately. However, this does not hold for qemu_co_enter_next. Now that qemu_co_queue_wait can synchronize (via QemuLockable) with code that is not running in coroutine context, it's important that code using qemu_co_enter_next can easily use a standardized locking idiom. First of all, qemu_co_enter_next must use aio_co_wake to restart the coroutine. Second, the function gains a second argument, a QemuLockable*, and the comments of qemu_co_queue_next and qemu_co_queue_restart_all are adjusted to clarify the difference.
