wasapi:
 - fixed occasional crash-bug which may be caused by a lightweight application that starts stream, checks if stream is running and if not terminates the stream: WASAPI implementation wasn't taking such behavior into account and stream termination (with structure deallocation) could happen during a thread start causing a crash on bad pointer usage
 - fixed Pa_IsStreamActive and similar not correctly reporting stopped stream if that was stopped from within a callback function (playback/capture) by returning paComplete
