Robert Watson 8a7d8cc675 - Combine kern.ps_showallprocs and kern.ipc.showallsockets into
a single kern.security.seeotheruids_permitted, describes as:
  "Unprivileged processes may see subjects/objects with different real uid"
  NOTE: kern.ps_showallprocs exists in -STABLE, and therefore there is
  an API change.  kern.ipc.showallsockets does not.
- Check kern.security.seeotheruids_permitted in cr_cansee().
- Replace visibility calls to socheckuid() with cr_cansee() (retain
  the change to socheckuid() in ipfw, where it is used for rule-matching).
- Remove prison_unpcb() and make use of cr_cansee() against the UNIX
  domain socket credential instead of comparing root vnodes for the
  UDS and the process.  This allows multiple jails to share the same
  chroot() and not see each others UNIX domain sockets.
- Remove unused socheckproc().

Now that cr_cansee() is used universally for socket visibility, a variety
of policies are more consistently enforced, including uid-based
restrictions and jail-based restrictions.  This also better-supports
the introduction of additional MAC models.
