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.

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

poll_frame()/request_frame() are used for audio too.

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

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

Those functions do only decoding now, encoding is run from
poll_filters().

Fixes an invalid write.

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