    kernel - Improve uidinfo
    
    * Improve uifind() to check td_cred for likely uid's, avoiding all
      locking on hits.
    
    * Create proc0 cred's cr_uidinfo and cr_ruidinfo using uicreate().
      All creds should now never have a NULL cr_uidinfo or cr_ruidinfo,
      so also remove conditionals that test for NULL.
