Avoid copying out kernel pointers from msgctl(IPC_STAT).

While this behaviour is harmless, it is really just an artifact of the
fact that the msgctl(2) implementation uses a user-visible structure as
part of the internal implementation, so it is not deliberate and these
pointers are not useful to userspace. Thus, NULL them out before
copying out, and remove references to them from the manual page.

Rename kernel-only members of semid_ds and msgid_ds.

This deliberately breaks the API in preperation for future syscall
revisions which will remove these nonstandard members.

In an exp-run a single port (devel/qemu-user-static) was found to
use them which it did becuase it emulates system calls. This has
been fixed in the ports tree.
