merge revision(s) 44517,44518,44519,44523: [Backport #9354]

	* lib/timeout.rb (Timeout#timeout): when a custom exception is given,
	  no instance is needed to be caught, so defer creating new instance
	  until it is raised.  [ruby-core:59511] [Bug #9354]

	* lib/timeout.rb (Timeout#timeout): should not rescue ordinarily
	  raised ExitException, which should not be thrown.

	* lib/timeout.rb (Timeout::ExitException.catch): set @thread only if
	  it ought to be caught.

	* lib/timeout.rb (Timeout::ExitException.catch): pass arguments
	  for new instance.

	* lib/timeout.rb (Timeout::ExitException#exception): fallback to
	  Timeout::Error if couldn't throw.  [ruby-dev:47872] [Bug #9380]

	* lib/timeout.rb (Timeout#timeout): initialize ExitException with
	  message for the fallback case.
