Previously it was partly only added to central functions called
internally, however if GCC would inline these into the public fuction, the
alignment attribute would not take effect.

Instead, add it to all public entry points to avoid these problems.

The generic code frees them as well. Since av_free was used to free them
instead of av_freep, this would result in a double free.

This simplifies the code and avoids using libavcodec-specific
avcodec_fill_audio_frame().

Mostly based on libavcodec's

Additionally change sizeof(type) into sizeof(var)

Use the formats.h API instead.

This is more consistent with naming in the rest of Libav.

Do not leak all the temp buffers.

Do not leak the x/y expressions.

Do not overwrite the variable set through AVOptions.

Do not overwrite the variables set through AVOptions.

Frame number should be incremented normally even if the link properties
change.

It should not be reinitialized if the link properties change.

Do not leak the initialized filter instance.

Do not leak the expressions.
