examples/muxing: honour distinction between encoder PTS timebase and stream timebase
...
Fix PTS set on the frame when encoding, which must be specified in the
encoder timebase or this will confuse the encoder.
When muxing the packet, the PTS/DTS generated by the encoder is then
rescaled to the stream timebase.

examples/demuxing_decoding: return error when no codec found
...
The open_codec_context function, when it fails to find a codec, now
return AVERROR(EINVAL) to signal an error.
Before it would return the stream index, which was always >= 0, and
continue as if a codec was found. This change make it fail faster,
instead of repeated failed tries to decode frames with no codec.

There is no reason why this should copy the audio data in a very
complicated way. Also, strictly write the first plane, instead of
writing the whole buffer. This is more helpful in context of the
example. This way a user can clearly confirm that it works by playing
the written data as raw audio.

This assumes one audio packet is decoded one time. This is not true:

Add function avfilter_graph_parse_ptr() and favor it in place of
avfilter_graph_parse(), which will be restored with the old/Libav
signature at the next bump.
If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the
Libav-compatible signature for avfilter_graph_parse().
At the next major bump the current implementation of
avfilter_graph_parse() should be dropped in favor of the Libav/old
implementation.
Should address trac ticket #2672 .
