Ok, new attempt. Require autoconf-2.60 in this branch.

This simplifies things quite a bit by entirely getting
rid of the m4 diversions which were messing things up.
Now we are using the built-in autoconf diversions the
way they were intended and the HELP output order is
preserved through the AC_PRESERVE_HELP_ORDER macro 
which was introduced in autoconf-2.59c

The next thing to clean up are the template warnings
and I want to get to the bottom of the cache warning
we generate as well.  Now that I fixed the _cv_ stuff, 
I am not sure that is still a valid warning.
