Use the new "Slab" context for some allocations in reorderbuffer.h.
Note that this change alone does not yet fully address the performance problems triggering this work, a large portion of the slowdown is triggered by the tuple allocator, which isn't converted to the new allocator. It would be possible to do so, but using evenly sized objects, like both the current implementation in reorderbuffer.c and slab.c, wastes a fair amount of memory. A later patch by Tomas will introduce a better approach.
