* ext/json: merge JSON 1.8.1.

  nurse/json@002ac27...e09ffc0
* Remove Rubinius exception since transcoding should be working now.
* Fix flori/json#162 reported by Marc-Andre
  Lafortune <github_rocks@marc-andre.ca>. Thanks!
* Applied patches by Yui NARUSE <naruse@airemix.jp> to suppress
  warning with -Wchar-subscripts and better validate UTF-8 strings.
* Applied patch by ginriki@github to remove unnecessary if.
* Add load/dump interface to JSON::GenericObject to make
  serialize :some_attribute, JSON::GenericObject
  work in Rails active models for convenient
  SomeModel#some_attribute.foo.bar access to serialised JSON data.
