* hash.c (rb_hash_replace): should copy ifnone.

* hash.c (rb_hash_dup): should preserve HASH_PROC_DEFAULT and
  HASH_DELETED flags.

* hash.c (rb_hash_shift): shift from empty hash should not return
  its default proc.

* hash.c (rb_hash_default_proc): new method. [new]

* array.c (rb_ary_aref): no need for Bignum check.

* array.c (rb_ary_aset): explicit Bignum check removd.

* numeric.c (fix_aref): normalize bignum before bit-op.

* bignum.c (rb_big_rand): max may be Bignum zero.

* bignum.c (rb_cstr_to_inum): should normalize bignums, to avoid
  returning fixable bignum value.

* bignum.c (rb_uint2big): there should be no zero sized bignum.

* ext/extmk.rb.in: extmake() that works properly for both tkutil
  (tk/tkutil.so) and digest/sha1.

* hash.c (rb_hash_equal): should check HASH_PROC_DEFAULT too.
