  Log:
  Add some DIAGNOSTIC code.
  While in userland, keep the thread's ucred reference in a shadow
  field so that the usual place to store it is NULL.
  If DIAGNOSTIC is not set, the thread ucred is kept valid until the next
  kernel entry, at which time it is checked against the process cred
  and possibly corrected. Produces a BIG speedup in
  kernels with INVARIANTS set. (A previous commit corrected it
  for the non INVARIANTS case already)
