Use zero_vector where appropriate.

* alloc.c (zero_vector): Define as Lisp_Object.  Adjust users
accordingly.
* lisp.h (zero_vector): New declaration.
* font.c (null_vector): Remove.
(syms_of_font): Remove initialization and staticpro.
(font_list_entities, font_find_for_lface): Change to use zero_vector.
* keymap.c (Faccessible_keymaps): Likewise.
