This aims to standardize the English used in the libavfilter
documentation, describing the same thing in the same way more often,
and significantly reduce the amount of outright errors, including
run-on sentences and sentence fragments.

Instead of using a fixed bitrate_idx, calculate a matching bitrate for
the XING header.

Using a fixed bitrate_idx causes tools such as file(1) and mediainfo(1)
to report wrong bitrate and bitrate mode when using CBR.

This simplifies the code, since we do not have to deal with a possibly
negative source index anymore.

negative sample_index is handled in the block above.

The correct "next" input sample is not the first sample of the
resampling buffer, but the center sample of the filter_length-sized
block at the beginning.
