The code this was originally derived from processed wrap and mic tokens using
 the same functions.  This required some contortions, and more would be required
 with the addition of xdr_buf's, so it's better to separate out the two code
 paths.

 In preparation for adding privacy support, remove the last vestiges of the
 old wrap token code.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
