Feature #11500: [RFC] rename Queue to UnboundedQueue

Then deprecate and warn on usage of "Queue"

Or maybe even call the new one "UnsafeQueue" :)

I think the name "Queue" causes too many people to use it without
knowing the consequences of unbounded memory growth and lack of backpressure.

In all cases I can think of, SizedQueue should be used instead of
current Queue since it will not cause a process to grow out-of-memory.

On the other hand, Ruby still has too many ways for users to shoot themselves in
the foot with unbounded memory growth:

• using IO#read with no length argument
• IO#gets on unknown data
• Net::HTTP or open-uri to slurp a big file into memory
• "SELECT" from a DB library with no LIMIT
  ... etc.

And having one extra guideline won't help less-experienced Rubyists at all...
