wangqr 5f326cc873 Correctly write float header when saving WAV audio clip 
Fix wangqr/Aegisub#56

wangqr 71894fd769 Fix bugs in ram audio provider 
There was some magic bit operations to calculate the cache block offsets. This only works when both bytes_per_sample and channels are power of 2. Originally the format is assumed to be int16 mono, which satisfies this requirement. However in case we use original audio data, the channels can be something not a power of 2 (e.g. for 5.1 channel audio the number of channels is 6). This will break the calculation. We rewrite the calculation, without using those bit operations.

wangqr 0336779735 Added experimental XAudio2 audio player 
Removed downsampling in FFMS2 and CreateConvertAudioProvider, to ensure we can get the original audio channels and data.

wangqr c1a4e0674b Move the ConvertAudioProvider into GetInt16MonoAudio function 
And use a dummy ConvertAudioProvider to keep backward compatibility.

wangqr 24d52bb1ee Clearly state int16 Mono of the audio provider in function name 
Most code assumes the audio provider is providing int16 single channel audio data, without actually checking them. In this commit, we add a new function to provide the needed int16 mono data with checking.
