* ext/json/*, test/json/*, defs/default_gems: Gemify JSON library.
[fix GH-867][Feature #11057] * test/ruby/test_extlibs.rb: removed json gem from existence extentions. * gems/bundled_gems: added json gem into bundled gem. * lib/rdoc/rubygems_hook.rb: ignored no json environment. * lib/rubygems/test_case.rb, test/rubygems/*: ditto. * lib/rdoc/test_case.rb, test/rdoc/*: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@50231 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
