Karl Blomster 0badb4059f 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).

Karl Blomster 893ff2f78a 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.
