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.
