Error caused by unalignment access on Sparc-Solaris (and possibly on
other similar environment.) This patch just do memcpy always instead
of checking architecture. I see no perf drop on my 64bit env. For
more details, see #4320.
* test/digest/test_digest.rb: add test for unalignment access.

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.

ext/digest/md5/md5init.c, ext/digest/rmd160/rmd160init.c,
ext/digest/sha1/sha1init.c, ext/digest/sha2/sha2init.c:
Introduce API versioning.
* ext/digest/digest.c, ext/digest/digest.h,
ext/digest/md5/md5init.c, ext/digest/rmd160/rmd160init.c,
ext/digest/sha1/sha1init.c, ext/digest/sha2/sha2init.c: Remove
the constants DIGEST_LENGTH and BLOCK_LENGTH and turn them into
instance methods digest_length() and block_length(). Class
methods with the same names are also provided, which take extra
parameters for a digest method.
* ext/digest/lib/digest/hmac.rb: Completely redesign the API which
is similar to Perl's, now that Digest classes can take hashing
parameters.

also to the trunk will assure compatibilities.
