clean up object print methods casetab.c, console.c, data.c, database.c, device-msw.c, device.c, eval.c, file-coding.c, frame.c, glyphs.c, gui.c, keymap.c, lisp.h, mule-charset.c, objects.c, print.c, process.c, tooltalk.c, ui-gtk.c, window.c: New function printing_unreadable_lcrecord(). Automatically prints the type name and pointer value of the object. Use it instead of printing_unreadable_object(); make that latter function local to print.c. window.c: During creation, window may have Qt as its buffer. Don't crash if trying to print such a window.
