Remove unnecessary casts involving pointers.

These casts are no longer needed now that we assume C89 or later,
since they involve casting to or from void *.
* alloc.c (make_pure_string, make_pure_c_string, pure_cons)
(make_pure_float, make_pure_vector):
* lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):
* macros.c (Fstart_kbd_macro):
* menu.c (find_and_return_menu_selection):
* minibuf.c (read_minibuf_noninteractive):
* sysdep.c (closedir):
* xdisp.c (x_produce_glyphs):
* xfaces.c (compare_fonts_by_sort_order):
* xfns.c (x_real_positions, select_visual):
* xselect.c (x_stop_queuing_selection_requests)
(x_get_window_property, x_get_window_property_as_lisp_data):
* xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
Remove unnecessary pointer casts.
* alloc.c (record_xmalloc): New function.
* lisp.h (record_xmalloc): New decl.
(SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
more like a function.  This is because the pointer cast is not
needed.  All uses changed.
* print.c (print_string, print_error_message): Avoid length recalc.
