* ext/bigdecimal: Workaround fix for bigdecimal test failures caused

Browse Source 
by [ruby-dev:47413] [Feature #8509]

* ext/bigdecimal/bigdecimal.h (BDIGIT): Make it independent from the
  definition for bignum.c.
  (SIZEOF_BDIGITS): Ditto.
  (BDIGIT_DBL): Ditto.
  (BDIGIT_DBL_SIGNED): Ditto.
  (PRI_BDIGIT_PREFIX): Undefine the definition.
  (PRI_BDIGIT_DBL_PREFIX): Ditto.

* ext/bigdecimal/bigdecimal.c (RBIGNUM_ZERO_P): Use rb_bigzero_p.
  (bigzero_p): Removed.
  (is_even): Use rb_big_pack.
