Add sha256, sha384 and sha512 digest algorithms, with BSD-licenced
code from Aaron Gifford.
Bump version number to 20010307
Simplify the manual page installation:
+ remove the :D.gz modifier from the manual page installation commands.
It's not necessary, as bsd.pkg.mk works out whether the manual page
is gzipped or not
+ just use the make(1) :M modifier to work out
whether catinstall and maninstall are set in ${MANINSTALL}
