  avcodec/asvenc: Don't waste bits encoding non-visible part
  
  Up until now, the encoder replicated all the border pixels
  for incomplete 16x16 macroblocks. In case the available width
  or height is <= 8, some of the luma blocks of the MB
  do not correspond to actual input, so that we should encode
  them using the least amount of bits. Zeroing the block coefficients
  (as this commit does) achieves this, replicating the pixels
  and performing an FDCT does not.
  
  This commit also removes the frame copying code for insufficiently
  aligned dimensions.
  
  The vsynth3-asv[12] FATE tests use a 34x34 input file and are
  therefore affected by this. As the ref updates show, the size
  and checksum of the encoded changes, yet the decoded output
  stays the same.

  avformat/movenc: Fix flush fragment
  
  The follow cmd output corrupted file before the patch:
  
  ffmpeg -f lavfi -i color=blue,trim=duration=0.04 \
  	-f lavfi -i anullsrc,atrim=duration=2 \
  	-movflags +empty_moov+hybrid_fragmented \
  	-frag_duration 1000000 \
  	-frag_interleave 1 \
  	output.mp4
  
  1. first_track is the first track with track->entry != 0. As in the
  command above, video track (track index 0) has a single frame. When
  flush the second fragment, first_track is 1, the audio track.
  
  2. write_moof = i == first_track, so write_moof is false for i = 0.
  
  3. When mov->frag_interleave != 0, mov->mdat_buf != NULL, because
  it contains audio data. So avio_write is called before write_moof,
  that is, the data write before moof, and mov_finish_fragment
  executed with wrong mdat_start.
  
  4. With normal fmp4 output, the error isn't obvious. With
  hybrid_fragmented, ffplay output.mp4 shows a lot of error messages.
