bf00a73ace dca: clear inactive subbands only once in qmf_32_subbands() 
Writing zeros to the high entries in the array need only be
done once as the cutoff position is constant throughout the
loop.

ecf31a68fd Show configuration and library version with AV_LOG_INFO. 
This partly reverts 1c5e9551bc,
a change of behaviour that was not discussed.

The reason for the revert is that FFmpeg cares about bugreports.

998e8519ef vf_unsharp: fix out-of-buffer read 
In apply_unsharp(), when y is >= height, prevent out-of-buffer reading
from src, read from the last buffer line in src2 instead.

The check was implemented in the original unsharp libmpcodecs code and
lost in the port.

This also fixes output discrepancy between the two filters.
