Hmm, the behaviour of the anti-skip buffer is still not quite
correct on the swcodec targets.

The anti-skip buffer is meant to be an *additional* buffer
margin for when the unit receives some bumping while rebuffering.

On archos it's implemeted like this. The standard low watermark
is calculated from the spinup time (using a safe default if not
yet available) plus a minimal margin, and the bitrate. The
anti-skip buffer is added to that, and it's possible to set it
to zero without causing skipping.

The swcodec implementation should be fixed, imho.
