bc6901c949 lavfi/af_atempo: clear references before returning error.
Once the frame has been given to ff_filter_frame(), it can
no longer be used, even on error.

Fix trac ticket #3430.

0c77cdb491 libavfilter/af_atempo: Avoid round-off error build-up, ticket #2484
Current method for constraining fragment position drift suffers from
round-off error build up.

Instead of calculating cumulative drift as a sum of input fragment
position corrections, it is more accurate to calculate drift as the
difference between current fragment position and the ideal position
specified by the tempo scale factor.

Memory obtained from av_realloc is not aligned enough for AVX.
The other similar allocations are changed too because they use

972cad77fa lavfi: remove unnecessary inclusion of libavcodec/avcodec.h in avfilter.h
libavfilter API was designed in order to be clarly distinguished from the
libavcodec API, including avcodec.h in avfilter.h is not going to help to
stick to this principle.

The inclusion of libavutil/audioconvert.h in many files was required
because avcodec.h includes audioconvert.h.

libavfilter/avcodec.h is where the lavc/lavfi interface should be
entirely placed.
