Fix an issue in recent walwriter hibernation patch. Users of asynchronous-commit mode expect there to be a guaranteed maximum delay before an async commit's WAL records get flushed to disk. The original version of the walwriter hibernation patch broke that. Add an extra shared-memory flag to allow async commits to kick the walwriter out of hibernation mode, without adding any noticeable overhead in cases where no action is needed.
