We do this to ensure that input_get_buffer is not called from a
frame_worker_thread of a multithreaded decoder when we already freed the
filters.

Fixes occasional segfaults on video stream change.

This fixes occasional segfaults caused by lock request of the packet queue from
the reader thread.

Also don't allow to put frames into the queue when it's aborted, and don't try
to fill the queue with frames when it is aborted.

Fix -vf copy with pal8 format.

Move AVPALETTE_SIZE and AVPALETTE_COUNT definition from
libavcodec/avcodec.h to libavutil/pixfmt.h.

The definition is more useful in libavutil, where it can be shared for
example by libavfilter and libswscale.
