Subject: [PATCH] Start adding VT100 support for Windows

The first parameter should be a stream (STDOUT or STDERR).

If no second parameter is specified: the function checks if the stream
supports VT100 control codes:
- Windows: returns TRUE if Windows is 10.0.10586 or greater, the
  console has the ENABLE_VIRTUAL_TERMINAL_PROCESSING flag and the
  stream is not redirected.
- POSIX: returns TRUE if the stream is not redirected.
- Others: returns FALSE

If the second parameter is specified: the function tries to enable or
disable the VT100 control codes.
- Windows: returns TRUE if Windows is 10.0.10586 or greater, the stream
  is not redirected and the ENABLE_VIRTUAL_TERMINAL_PROCESSING flag has
  been set/unset
- Others: returns FALSE
