don't use MAKE_PTR/OFFSET for shmem pointers

Since we require every process to map the shared memory region to the same
address, we don't need the MAKE_PTR/OFFSET code that was needed when that
was not the case. This patch makes shared memory pointers just like
regular pointers.

Applied with minor editorialization --- mainly, I converted a couple of
"void *" pointer declarations to more specific types, since it seems to
me the main point of this is to not use nonspecific pointers
unnecessarily.

We now have two very similar doubly-linked list implementations. Should
we take one of them out?

If you're thinking of dllist, it has considerably different implementation
assumptions.
