sprintf() is unsafe since it may overflow the bounds
of its destination buffers. Remove the last of the
calls to it; all the logic has either been rewritten
to use snprintf() or other forms of string copying
such as strlcpy().

This is the big push to get rid of the last of the
unadorned dynamic arrays. Use ptr_vectors for things
like mail conferences etc.
Lots of incidental cleanup along the way.
