New cksumtype split (safe_cksum vs. req_cksum)

The initialization of the checksum types does not easily permit the
specification of checksum types per enctype being used.  For instance,
when I have des3-sha enabled, I want it to be using sha & hmac-sha, not
md5.  The initialization code seems to read in only one integer, instead
of a list of enctype/cksum mappings...  Of course, I also don't expect
if I set it to using sha all the time that the services that only have a
des key registered necessarily have been updated to know anything but
md5 or crc.

Btw, other than that, des3 works like a champ -- although I wouldn't
count on the algorithm not changing again... However, this time, I
expect there to only be minor changes, now that it has received so much
review.
