Changed how the lavc audio decoder handles non-decodable audio packets. Previously, if decoding failed at any point in the audio stream, it would throw an exception that didn't get caught anywhere and hence crashed the program. Now, it'll just silently skip the broken packet and go on to next one, meaning that if the audio stream is actually corrupted and not just some weird stream with null packets you'll either get desyncs from the missing samples, or if the entire stream is non-decodable you'll just silence.

Restructured audio providing a bit. If a provider cannot provide 16-bit mono audio with a sample rate higher than 32kHz, an intermediate converting provider will be inserted to fix it. Made the lavc audio provider rely on this for downmixing instead of doing it with libavcodec (used to fail on audio with >2 channels).

Major rewrite of the video providing system. Hilights:
...
- It is now the responsibility of each video provider to provide a list of keyframe positions and (if it can) timecodes.
- The ffmpeg video provider now indexes files before opening them and does no longer rely on stream->duration to determine the number of frames. Fixes opening of MKV files, but it does not (currently) open timecodes automatically and reported keyframe positions seem way off. Status of frame-accuracy with MKV files unknown but it may very well work.
- Modified the way the ffmpeg video provider seeks (inspired by code from Myrsloik's ffmpegsource). Should no longer lose the first frame and should also no longer be frame-inaccurate, at least not with AVI.
- DirectShow video provider may or may not be completely broken, not tested.
