Preparation for lane:close() and correct to-be-closed variables

* lane:join() can no longer be used to read yielded values
* same with lane indexing
* stub for lane:close(), similar to coroutine.close() (not implemented yet)
* preparing tests for to-be-closed variables in yielded coroutine lanes
* yielded lanes unlock and terminate properly at Lanes shutdown
