cleanup: Queue and Bounded_queue

Browse Source 
Bounded_queue<> pretended to be a typesafe C++ wrapper
on top of pure C queues.h.

But it wasn't, it was tightly bounded to filesort and only useful there.

* implement Queue<> - a typesafe C++ wrapper on top of QUEUE
* move Bounded_queue to filesort.cc, remove pointless "generalizations"
  change it to use Queue.
* remove bounded_queue.h
* change subselect_rowid_merge_engine to use Queue, not QUEUE
