i_length is not specific to linear audio, so it cannot be removed so
easily. And the proper conversion from samples to length date_t or
something similar (yes, I know it is not always used)...
For samples, I don't mind removing it *if* they are only used for decoded
audio. However I doubt that is the case, and a lot of divisions with
variable divisor would be added :-( I won't do it myself.
In this particular case, I think it would be far simpler to copy the
samples and length in the 9 indirect conversions.
