Feature #8639: Add Queue#each

I was fiddling around with Queue the other day and realized it doesn't have an #each \
method. So I made one: https://github.com/ruby/ruby/pull/361

As for why, it makes for a convenient way to build consumer processes:

  inq = Queue.new
  outq = Queue.new
  doubler = Thread.new do
    inq.each do |n|
      outq << n + n
    end
  end

My PR also returns an Enumerator when no block is given, and handles the non_block \
argument.

I'm sure there's some good reason that this method wasn't there already, so feel free \
to explain.

Also, this is my first Ruby feature ticket so please let me know if I'm missing any \
points of protocol.

Thanks!
