Stabilize ddd type definitions

Some cleanup of the ddd type definition code.

As a by-product, this should fix !166 (closed).

mentioned in merge request !166 (closed)

I added a commit (in my fork, I can't push here) which finishes fixing the undefined behavior. Clang-10 with -fsanitize=undefined -fno-sanitize-recover=undefined now does not report any undefined behavior in typemgr.cc or initddd.cc (it still does in gm/gm.h, gm/enrol.cc and gm/ugm.cc).

Instead of casting the desc->bnd_size and desc->inner_size to size_t, we could also just change their type to size_t, but I wasn't sure if that would cause some problems elsewhere.

Thank you, I ran out of time to finish this MR yesterday. I'll finish and merge it no later than monday.

(it still does in gm/gm.h, gm/enrol.cc and gm/ugm.cc).

Can you open a separate issue for that, with some more information?
