alex 3b5bff74db Pass an actual empty environment to execle() as per POSIX rather than
rely on undocumented behavior.

The following fixes were obtained from OpenBSD:

  o -Wall fixes to tlist array initialization and assignment used
    as truth value.
  o Use a restricted environment.
  o Improved error message when shutdown fails to exec reboot or halt.
