rb_ to avoid name clash in writing extensions. * ext/digest: Introduce Digest::Class and Digest::Instance for ease of implementing subclasses and add-ons, inspried by gotoyuzo. * ext/digest: The Digest::Instance module now requires and assumes that any instance be resettable and clonable, and add some convenient instance methods such as "new()", for creating a new copy, parameter taking "digest()" and "hexdigest()", for instant calculation. These methods make digest instances work just like digest classes. * ext/digest/sha2/lib/digest/sha2.rb: Add the Digest::SHA2 class to wrap up SHA2 variants: SHA256, SHA384 and SHA512, hoping this module would make a decent example of a digest subclass written in Ruby. * ext/digest/lib/digest.rb: Adjust autoload entries for SHA2 classes. * ext/digest/lib/digest/hmac.rb: Follow the framework updates. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@11197 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
