Rename lots of things, THIS BREAKS THE AEGISUB BUILD because of changed exported type and function names. Fixed an uninitialized memory bug that would make it crash on unindexed audio tracks in mastroska. Made ffms.h C-friendlier. Exports the start time of an audio track in the audio properties. Less signedness and type conversion warnings. Originally committed to SVN as r2940.
