Subject: [PATCH] lavr: Do not change the sample format for mono audio

This treats mono as planar internally within libavresample rather
than changing the sample format.

Subject: [PATCH] lavr: fix mixing matrix reduction when normalization is disabled

In some cases when an input contributes fully to the corresponding
output, other inputs may also contribute to the same output. This is the
case, for example, for the default 5.1 to stereo downmix matrix without
normalization.
