message:
  * font.h (struct font_entity) [HAVE_NS]: New field to record
  font driver which was used to create this entity.
  (struct font) [HAVE_WINDOW_SYSTEM]: New field to record
  frame where the font was opened.
  (font_close_object): Add prototype.
  * font.c (font_make_entity) [HAVE_NS]: Zero out driver field.
  (font_close_object): Not static any more.  Lost frame arg.
  Adjust comment and users.
  * alloc.c (cleanup_vector): Call font_close_object to adjust
  per-frame font counters correctly.  If HAVE_NS, also call
  driver-specific cleanup for font-entity objects.
  * ftfont.c (ftfont_open):
  * nsfont.m (nsfont_open):
  * w32font.c (w32font_open_internal):
  * xfont.c (xfont_open):
  * xftfont.c (xftfont_open): Save frame pointer in font object.
  * macfont.m (macfont_open): Likewise.
  (macfont_descriptor_entity): Save driver pointer to be able
  to call its free_entity routine when font-entity is swept.
  * ftxfont.c (ftxfont_open): Add eassert because frame
  pointer should be saved by ftfont_driver.open.
