First example and test of private codec parameters.

Originally committed as revision 25258 to svn://svn.ffmpeg.org/ffmpeg/trunk

Move allocation and init to defaults of the private codec contexts to avcodec_get_context_defaults3().
That way the user app can set codec specific parameters in the private context
before opening it.

r25218 made assumptions about the existence of past reference frames that
weren't necessarily true.

Originally committed as revision 25243 to svn://svn.ffmpeg.org/ffmpeg/trunk

Because DTS values aren't passed through decoders, they tend to be
inaccurate if decoder delay doesn't match what was expected by the encoder.

In particular this improves timestamps for H.264 without num_reorder_frames
set and with -strict 1, which causes DTS to be up to 16 frames ahead of the
picture.

Note that this doesn't really improve any file with very broken PTS/DTS,
since PTS isn't much more accurate in these.
