Import of a small utility, which calculates message digests, into the

NetBSD packages collection.

At the current time, this utility calculates md5, sha1 and rmd160
message digests, but is designed to be extensible, so that other
algorithms can be added easily, if and when they appear.

The utility outputs digests in the same format as md5(1) in basesrc.

It is designed to be small, and to be linked statically.
