Merge r180610, r180616, r180673 from head to stable/7:

  Add DDB "show conifhk" command, which lists hooks currently waiting
  for completion in run_interrupt_driven_config_hooks().  This is
  helpful when trying to figure out which device drivers have gone
  into la-la land during boot-time autoconfiguration.

  Rather than simply waiting silently and indefinitely for all
  interrupt-driven configuration handlers to complete, print out a
  diagnostic message every 60 second indicating which handlers are
  still running.  Do this at most 5 times per run so as to avoid
  scrolling out any useful information from the kernel message
  buffer.

  The interval of 60 seconds was selected based on a best guess as
  to the nature of "long enough" and may want to be tuned higher
  or lower depending on real-world tolerances.

  If run_interrupt_driven_config_hooks() waits 360 seconds and INVARIANTS
  is compiled into the kernel, then panic.

  Discussed with: scottl
