* ext/digest, test/digest/test_digest.rb: Merge from trunk:
- Introduce versioning in Digest::Base API, and prefix C constants with RUBY_ and C type names with rb_ to avoid name clash in writing extensions. - Introduce Digest::Class and Digest::Instance for ease of implementing subclasses and add-ons. - Digest::Instance module requires and assumes that any instance be resettable and clonable. An instance method #new() is added so digest instances work just like digest classes. - The constructor does no longer take an initial string to feed; digest() and hexdigest() now do, instead. This allows digest classes to take their own hashing parameters. - Make some changes to digest() and hexdigest() class methods, which now take extra arguments, which are passed through to the constructor in an internal call. - Add #digest_length/size/length() and #block_length(), - 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. - Rip BubbleBabble support out of the base class and have a separate module named digest/bubblebabble. - Remove RD documents in favor of newly written and embedded RDoc documentation. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_1_8@11223 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
