The new function provides a more flexible interface for peeking at a
FIFO buffer data.

In lavfi_read_header(), use the pad index designated in the inout for
linking an output to a sink, rather than always 0. Fix link creation
for filters with more than one output (e.g. the split filter).

Custom PAR num/denum are coded -1.

FFmpeg writes data_size as AU_UNKNOWN_SIZE, make demuxer not
fail when data_size is set to this value.
Should fix trac issue #394.

* qatar/master:
  swscale: add dithering to yuv2yuvX_altivec_real
  rv34: free+allocate buffer instead of reallocating it to preserve alignment
  h264: add missing brackets.
  swscale: use 15-bit intermediates for 9/10-bit scaling.

Also drop obfuscating CHROMA_WIDTH/HEIGHT macros.

More consistent with the original libmpcodecs code, and the name
"unsharpen" was confusing.

It just does that part in scalar form, I doubt using a vector store
over 2 array would speed it up particularly.

The function should be written to not use a scratch buffer.

New syntax contains an optional stream type, allowing to refer to n-th
stream of specific type.

Omitting stream number now maps all streams of the given type.

They are confusing, irregular and redundant -- -map already contains all
the information.  Stream maps can now be parsed in opt_output_file().

Add a more user-friendly default behavior in case no maps are present.

Breaks -programid for now, but it never worked properly anyway. A better
solution will be written soon.

User applications should by now be able to support float encoders.
