  fftools/ffmpeg: Log exit code on exit
  
  When viewing logs, there are situations where it is not entirely
  clear whether ffmpeg CLI has exited gracefully. The two primary cases
  are
  
  - A crash/segfault has occured
    Windows for example doesn't output any message to the calling shell
  - The process has been terminated (e.g. killed externally)
  
  Printing a message on exit provides a reliable indication that the
  process has exited normally.
  Printing the exit code is useful as it usually remains invisible
  and unnoticed by users running FFmpeg from a shell.

  fftools/ffmpeg: Include elapsed-time in print_report()
  
  It's a highly useful metric, both at runtime and when viewing logs.

  fftools/ffprobe: Disable stderr buffering on Windows
  
  An identical call exists in ffmpeg.c
  
  With POSIX/glibc, stderr is already unbuffered (or line-buffered when
  a terminal is connected), but not in case of MSVCRT.
  Explicitly calling setvbuf() like in this commit, makes the Windows
  runtime behave like POSIX, giving the same “print immediately” behavior.
