James Zern 89f774e61d mux{edit,internal}: fix leaks on error 
several calls to ChunkSetHead() were unchecked, causing the chunk to
leak should the call fail due to OOM

Tested:
for i in `seq 1 1125`; do
  export MALLOC_FAIL_AT=$i
  ./examples/gif2webp gif_file
  ./examples/gif2webp -mixed gif_file
done
for i in `seq 1 171`; do
  export MALLOC_FAIL_AT=$i
  ./examples/img2webp jpeg_file -o /dev/null
  ./examples/img2webp -mixed jpeg_file -o /dev/null
done

WebP codec is a library to encode and decode images in WebP format. This package contains the library that can be used in other programs to add WebP support, as well as the command line tools 'cwebp' and 'dwebp' to compress and decompress images respectively.

See https://developers.google.com/speed/webp for details on the image format.
