	                          md5.pm 

Log message:
turn the checksums stored in packing elements into real objects, so that
pkg_add becomes mostly independent of the type of checksum stored.

separate md5 into an abstract OpenBSD::digest class and an md5 subclass
with specific methods to compute checksums and serialize results, and create
an sha class that does the same thing with sha256 (with a base64 serializer)
