ao_wasapi: Split into 2 files ao_wasapi.c was almost entirely init code mixed with option code and occasionally actual audio handling code. Split most things to ao_wasapi_utils.c and keep the audio handling code in ao_wasapi.c.

ao/wasapi: make functions return bool that were acting like it this involved inverting the logic of find_formats, enumerate_devies and wasapi_fill_VistaBlob. The latter two were trivial as their return values were not actually checked (to be fixed in a later commit).

ao_wasapi: simplify hotplug Take advantage of the fact that list_devs is called with a hotplug_inited ao. Also eliminate unnecessary nested function abstraction of hotplug_(un)init and list_devs. However, keep list_devs in ao_wasapi_utils.c since it uses the private functions get_device_id, get_device_name and exposing these would require including headers for IMMDevice in ao_wasapi_utils.h.

void wasapi_list_devs(struct ao *ao, struct ao_device_list *list);
ao/wasapi: tidy up better on failure Before, failures, particularly in the thread loop init, could lead to a bad state for the duration of mpvs execution. Make sure that everything that was initialized gets properly and safely uninitialized.

ao/wasapi: use atomic state variable instead of different events Unfortunately, because we have proxy objects (pAudioVolumeProxy, pEndpointVolumeProxy, pSessionControlProxy) it looks like we still have to use MsgWaitForMultipleObjects and watch for and dispatch pending messages: https://msdn.microsoft.com/en-us/library/windows/desktop/ms680112%28v=vs.85%29.aspx

ao/wasapi: improve error messages and add more debug statements also enforce more consistency in the exit codes and error handling thanks to Jonathan Yong <10walls@gmail.com>

ao/wasapi: make calling of thread_init consistent with thread_uninit

void wasapi_thread_uninit(struct ao *ao);
ao_wasapi: Move non-critical code outside of the event thread Due to the COM Single-Threaded Apartment model, the thread owning the objects will still do all the actual method calls (in the form of message dispatches), but at least this will be COM's problem rather than having to set up several handles and adding extra code to the event thread. Since the event thread still needs to own the WASAPI handles to avoid waiting on another thread to dispatch the messages, the init and uninit code still has to run in the thread. This also removes a broken drain implementation and removes unused headers from each of the files split from the original ao_wasapi.c.
