grep: replace the internal queue with a ring buffer
We know up front how many items we can have in the queue (-B/Bflag), so
pay the cost of those particular allocations early on.
The reduced queue maintenance overhead seemed to yield about an ~8%
improvement for my earlier `grep -C8 -r closefrom .` test.
