dwt: return errors from ff_slice_buffer_init()
x86: lavc: use %if HAVE_AVX guards around AVX functions in yasm code.

This is needed for older versions of yasm/nasm that do not support AVX.

asyncts: reset delta to 0 when it's not used.

Fixes an invalid write.
avconv: rename transcode_audio/video to decode_audio/video.

Those functions do only decoding now, encoding is run from
poll_filters().
avfiltergraph: smarter sample format selection.
lavfi: deprecate default config_props() callback and refactor avfilter_config_links()

Link properties have to be checked after config_props() is called to
make sure everything is sane, so the default config_props() for output
links was redundant.

Remove now empty defaults.c

lavfi: remove avfilter_default_* from public API on next bump.

Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.
lavfi: remove avfilter_null_* from public API on next bump.

Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.
lavfi: fix incorrect comment.

poll_frame()/request_frame() are used for audio too.
lavfi: fix comment, audio is supported now.
avio: Add a function for signalling end of reading/writing

tcp: Allow signalling end of reading/writing

tcp_shutdown() isn't needed at the moment, but is added for
consistency to explain how the function is supposed to be used.

lavu/pixfmt: move AVPALETTE_SIZE and _COUNT to pixfmt.h

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.
