Bug Description

Successor of https://bugs.launchpad.net/mixxx/+bug/1490580

It turns out that the conversion from stream units (100 ns) to sample frames might be inaccurate due to rounding errors. The calculated position in frames within the stream is sometimes 1 less than the actual position when using StreamUnitConverter::toFrameIndex(), although adding the frame index bias should already account for and prevent this situation.

Example:
http://psycle.free.fr/josepma/mixxxm4abug/DHT%20-%20True%20love%20(Makina%20Mix)%20-%20bad.m4a

Waveform analysis always stops at the same position:
Warning [AnalyzerQueue 1]: AnalyzerQueue - Aborting analysis after failed to read sample data from "C:/Users/uk/Music/Mixxx Library/DHT - True love (Makina Mix) - bad.m4a" : expected frames = [1323008 -> 1327104) , actual frames = [11156506 -> 11156506)
