Improve integer range checking
* src/bignum.c (check_integer_range, check_uinteger_max)
(check_int_nonnegative): New functions.
* src/frame.c (check_frame_pixels): New function.
(Fset_frame_height, Fset_frame_width, Fset_frame_size): Use it.
* src/lisp.h (CHECK_RANGED_INTEGER, CHECK_TYPE_RANGED_INTEGER):
Remove these macros. Unless otherwise specified, all callers
replaced by calls to check_integer_range, check_uinteger_range,
check_int_nonnegative.
* src/frame.c (gui_set_right_divider_width)
(gui_set_bottom_divider_width):
* src/nsfns.m (ns_set_internal_border_width):
* src/xfns.c (x_set_internal_border_width):
Using check_int_nonnegative means these functions no longer
incorrectly reject negative bignums; they treat them as 0,
just like negative fixnums.
