64c06615d2 vsrc_buffer: simplify av_vsrc_buffer_add_frame*() interface 
Now that pix_fmt, width, and height are directly embedded in the AVFrame,
there is no need to pass these values as separate arguments.

01042d4123 lavc: set defaults in internal codec frames 
This is required specifically for setting frame->format to -1,
otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading
the format from the output decoded frame will get misled.

In particular fix regressions occurring with the pending vsrc_buffer
patch.

a851fa7fec ffmpeg: move resample_changed check within the #if !CONFIG_AVFILTER 
The check and the corresponding message in do_video_out() are
unnecessary in the libavfilter path, as a similar check and message
are performed within the buffer source.

f5a669c229 ffmpeg: simplify mid-stream reconfiguration when libavfilter is disabled 
Implement lazy initialization of the image resample context, so that
the initialization code does not need to be duplicated.

Also manage the case in which resample/size change mid-stream. For
each packet the code computes if resampling is needed.

Previously the resample check was done only at the initialization, in
case size/format changed and no resample was detected at the init
stage ffmpeg was silently exiting.

566666caf3 lavfi: add libavfilter/avcodec.h and avfilter_copy_frame_props() 
avfilter_copy_frame_props() avoids code duplication and increases
robustness.

The added files libavfilter/avcodec.[ch] are used for containing
utilities useful for gluing togheter libavfilter and libavcodec.

18ded93ab3 lavc: add format field to AVFrame 
The format is a per-frame property, having it in AVFrame simplify the
operation of extraction of that information, since avoids the need to
access the codec/stream context.

d62bf5d4e7 mp3enc: mux a XING header 
The patch below provides exactly that to the MP3 muxer. A XING header
containing

   * the numer of frames,
   * the size, and
   * a TOC

is generated.

It's based on an idea by Anton Khirnov (restricted to the number of
frames) found at

   http://patches.ffmpeg.org/patch/1891/

The TOC is generated as found in lame's "VbrTag.c".

According to my tests the following reproduces the number of frames, the
size and the TOC in "c.mp3" from "b.mp3" (except a shift due to shorter
XING header generated by FFmpeg):

   lame -V2 a.wav b.mp3
   ffmpeg -i b.mp3 -acodec copy -y c.mp3
