* hash.c (rb_hash_initialize): now accepts a block to calculate
  the default value. [new]

* hash.c (rb_hash_aref): call "default" method to get the value
  corrensponding to the non existing key.

* hash.c (rb_hash_default): get the default value based on the
  block given to 'new'.  Now it takes an optinal "key" argument.
  "default" became the method to get the value for non existing
  key.  Users may override "default" method to change the hash
  behavior.
