Subject: [PATCH] * bignum.c (rb_big_hash): make it public function to be
 available in   other source files, and remove documentation comment for
 Bignum#hash.

* bignum.c (Bignum#hash): remove its definition because it is unified
  with Object#hash.

* include/ruby/intern.h (rb_big_hash): add a prototype declaration.

* hash.c (any_hash): treat Bignum values directly.
