  MFC to RELENG_5:
  
  | Fix system shutdown timeout handling by again supporting longer running
  | shutdown procedures (which have a duration of more than 120 seconds).
  |
  | We have two user-space affecting shutdown timeouts: a "soft" one in
  | /etc/rc.shutdown and a "hard" one in init(8). The first one can be
  | configured via /etc/rc.conf variable "rcshutdown_timeout" and defaults
  | to 30 seconds. The second one was originally (in 1998) intended to be
  | configured via sysctl(8) variable "kern.shutdown_timeout" and defaults
  | to 120 seconds.
  |
  | Unfortunately, the "kern.shutdown_timeout" was declared "unused" in 1999
  | (as it obviously is actually not used within the kernel itself) and
  | hence was intentionally but misleadingly removed in revision 1.107 from
  | init_main.c. Kernel sysctl(8) variables are certainly a wrong way to
  | control user-space processes in general, but in this particular case the
  | sysctl(8) variable should have remained as it supports init(8), which
  | isn't passed command line flags (which in turn could have been set via
  | /etc/rc.conf), etc.
  |
  | As there is already a similar "kern.init_path" sysctl(8) variable which
  | directly affects init(8), resurrect the init(8) shutdown timeout under
  | sysctl(8) variable "kern.init_shutdown_timeout". But this time document
  | it as being intentionally unused within the kernel and used by init(8).
  | Also document it in the manpages init(8) and rc.conf(5).
