packets subtitles (like dvdsub) stay indefinitely.

start_display_time was also ignored, but is it almost always 0.

Use av_realloc instead of av_realloc_f to keep the original
array in case of failure: it is freed in full by the fail label.

Use this in VP8/H264-8bit loopfilter functions so they can be used if
there is no aligned stack (e.g. MSVC 32bit or ICC 10.x).

This allows AudioMix to be treated the same way as other conversion contexts
and removes the requirement to allocate it at the same time as the
AVAudioResampleContext.

The current matrix get/set functions are split between the public interface
and AudioMix private functions.
