Robert Watson 6f6174a762 Improve the consistency of MAC Framework and MAC policy entry point
naming by renaming certain "proc" entry points to "cred" entry points,
reflecting their manipulation of credentials.  For some entry points,
the process was passed into the framework but not into policies; in
these cases, stop passing in the process since we don't need it.

  mac_proc_check_setaudit -> mac_cred_check_setaudit
  mac_proc_check_setaudit_addr -> mac_cred_check_setaudit_addr
  mac_proc_check_setauid -> mac_cred_check_setauid
  mac_proc_check_setegid -> mac_cred_check_setegid
  mac_proc_check_seteuid -> mac_cred_check_seteuid
  mac_proc_check_setgid -> mac_cred_check_setgid
  mac_proc_check_setgroups -> mac_cred_ceck_setgroups
  mac_proc_check_setregid -> mac_cred_check_setregid
  mac_proc_check_setresgid -> mac_cred_check_setresgid
  mac_proc_check_setresuid -> mac_cred_check_setresuid
  mac_proc_check_setreuid -> mac_cred_check_setreuid
  mac_proc_check_setuid -> mac_cred_check_setuid
