message:
  Backport bug 7517 fixes from trunk.
  
  * coding.h (ENCODE_UTF_8): Remove "Used by ..." comment.
  
  * nsfns.m (ns_set_name_iconic): Remove.
  (ns_get_screen): Don't assign integer to f.
  (ns_set_name_internal): New function.
  (Vicon_title_format): Extern declare.
  (ns_set_name): Call ns_set_name_internal.
  (x_explicitly_set_name): Remove call to ns_set_name_iconic.
  (x_implicitly_set_name): Ditto.
  (x_set_title): Remove commet about EXPLICIT.  Call ns_set_name_internal.
  (ns_set_name_as_filename): Encode name with ENCODE_UTF_8.
  Always use buffer name for title and buffer filename only for
  RepresentedFilename. Handle bad UTF-8 in buffer name (Bug#7517).
