FFmpeg: Create, use av_err2string() (#689)

Browse Source 
- Previously 'av_make_error_string' was defined in FFmpegUtilities.h
  for the sole purpose of redefining `av_err2str()` as a call to that
  function. `av_err2str()` was then used in our code, often in string
  contexts where its output was cast to `std::string`.
- Since that was excessively circular, instead the function is named
  `av_err2string()`, and it's used directly in contexts where a
  std::string is expected.
- `av_err2str()` is still #defined as `av_err2string(...).c_str()`
